People complaining means they care about the game. The opposite of love is indifference. I can appreciate the new look of most of the new models and the updated atmosphere. That said, can you imagine if games like Nikke, or some other mobile gacha game kept showing off sneak peeks of new characters and never made them playable? Players would be justifiably upset. Teasers/trailers/previews are neat, but some folks want substance. Personally, I think it's awesome that snats has made a catalogue of 100+ unique looking models. However, it does seem like a waste of time to some people, when they see development time between updates going up and playable content is lessened. Now, this might be not be the case, but the perception is longer update, for reworked/remade content and there is less than the previous version of the game.
As for me, I check back here periodically, because I like the game and I thought the premise was interesting and I am hopeful that when all the pieces are in place it could be one of the best games on this site.
