trash battles aren't as balanced in lot2 either imo. like in lot1 trash battles were more or less more and more difficult after every floor, and after you reach floor 13 each battle is exciting based on its challenge unless you were currently using a top tier trash cleaner in your group at that moment like flan, mystia, etc. Exceptions were those effing shadowcats on floor 2 which are balanced to be on floor 31 or something (yes I know it doesn't exist), slash diving zord fishes on 13f (the floor as a whole is actually easier than previous ones imo minus the chance of those fish), and 17f if you do not have a good fast aoe physical nuke when those gems appear.... Even the minibosses on 20f in lot1 were more exciting, both for potential loot drops, and challenge, and reward. Given the fact that you only lose 10tp when a character loses all their hp instead of being sent back to town in lot2, I think they should have been made alot more challenging a lot sooner than... I forget what floor it was where they finally started being a threat. 16f or 17f I believe.
However I do notice that most floors seem to have rarespawn trash enemies that are far more powerful but don't quite qualify as minibosses either. like on 4f there are 2 knights, one is level 12 and another 24 iirc, obviously I'm talking about the level 24 one, and 6f has sharks, and as a rare spawn there's some metal coloured shark. I don't really remember lot1 having this except for perhaps the solar demons on 19f.
It's really strange. lot2 is both more and less polished. I think the developer made some great advancements in terms of character customization, subclasses, acheivements that actually matter, etc. But in doing so he lost the ability to spend as much time/effort balancing the game from start to finish as effing masterfully (imo) as he did the first time. I wonder if it was that, or if 1 was just a crazy fluke on his part in that regard.
