As you progress, get money, build up friendship with NPCs, you'll get more crits on work, better stat gain, and with some warden perk, can even start with 4 points already in some stats.
The point of the stat reset is so you can adapt your strategy for next fight. Big hitting guy, need more defense, evading guy, need more crit and precision, that sort of thing. If stats didn't reset, you'd max them before you even finish underground league then rest is cakewalk, hell, with legendary gear, you don't even need the stats ahah
