That said, everything was balanced with normal difficulty mode in mind, and while hardcore difficulty is taken into account, it can be vastly more difficult. I hope sheds some light on at least some of the existing mechanics.
As long as you don't have to wait for weeks until Slyth catches up Gryff, I'm fine. While it was no issue in original WT with favors up to 25-pt range, it got really annoying when you are in the 50-pt range and Sylth compensates only every other day with +17 or something while Gryff also gets its regular pts. The other two houses with their pts haven't been very helpful so far, but I haven't played WT and in partuclar the other diffs of WTS enough to judge that properly.
I possibly give HC a try next time and see how quickly it gets frusted. If someone isn't that interested in purchasing outfits without a quest/event purpose then gold shouldn't be such an issue either.
Here are some ideas for future content that came into my dirty mind:
Granger: her content is large enough since the original game. Just some more sexual interaction with Cho, Luna, Tonks, etc. would spice the final phase up. The crush between Cho and Granger is obviously still unresolved.
Cho: the latest confession scene with her is extremely lengthy to a degree that it is more torture than pleasure in the end. Some follow-up shorter action, like having some sex would do well. Even some chibi animations as placeholder would do fine at first before it gets replaced by CGI animations. By all means, ending her content with zero repetitive actions left to do is not the way how you want to leave a girl behind in the end.
Adding more like a continuation with Tonks for more action is highly in demand too.
The old Luna normal-route content is the best example how to do a repetitive final phase in the end that satisfies well enough.
Susan: after cracking her insecurity during the last imperio lecture with Astoria, it’s really about time to have some simple let’s-do-it fun with Susan as freebie actions afterwards. Her profile reveals her secret crush on the headmaster, so there is no real need for further chit chat and such. Some silly chibi animations would do fine and feel like Susan is another accomplishment in the end, and not someone you don’t bother to invite to your office at all all the time.
Astoria: she’s indeed a frigid bitch and hard to crack. Tonks seems most interested and possibly the only one who could convert her to a slut too, as Astoria has expressed her disgust to the Old Man often enough. If that is mixed by further sexual torture with Susan, like some silly lactating spell/potion effect, that would be perfect. Astoria could have a crush for Susan but it’s much more hidden than with Cho and Granger. A challenge for Genie and Tonks to solve.
Luna: well, the v1.40+ content replacement still lies deep in the shadow of its removed content of v1.39. Having sex is at least the next logical step with possible additional action with Tonks and Granger. The game really needs more orgies. There must be a good reason why the Ministry of Magic finally intervened with an extensive memory wipe according to Snape’s story in Star Channel 34.
Tonks: the one with the most potential for expansion. I can’t wait for the next new content. Additional personal requests besides her public ones comes quickly into one’s mind. She is interested in Genie after all, so this lack is the biggest blue-ball issue. Tonks is the best partner for moresomes: Cho content already started well, cracking Astoria is still unfinished, Susan is another possibility, same for all the other girls. She’s easily a match for Genie's sexual appetite for more after all.
Snape: let’s not forget about this bastard. Some nasty threesome scenes with Grangers comes into one’s dirty mind in the final phase. No need to get touchy with Snape, rather only the back and front sharing fun similar like the dance/strip event.
He is famous for barging into the most undesired situations, so can play as a joker to whatever other future content scene. Even some small scenes were Genie surprises him in Snape’s room together with a Slyth girl could offer some additional fun. If Snape doesn’t come up sending his girls to Genie, it’s time for a surprise visit as revenge.
Ginny: possibly the most missed character in WTS that finally made an appearance in Star Channel 34; story-wise afterwards. I can’t remember all her sentences there at moment, but her interest in the headmaster same like Susan is there and how often she is mentioned during WT(S). That screams for an appearance in WTS too. I’d still rather expand the existing characters first though to a satisfying end, as long as there is no further idea to expand an existing or future scene. At least a single, special guest appearance during one of the Granger events would be awesome that explains her sexual desire in the SC34 scene when the memory wipe dissolves.
