lots of lonestar hate going on in here for him being OP. Honestly post patch, I think he's probably the most balanced character now alongside Leon and I don't have any real issues with them. On the other hand some characters do need a few changes to balance it out across the board.
Froggy G is probably the best character now due to his thorn fish change, hes the new lonestar piggy boots missile. The way his gun upgrades work with it now is very broken compared to other characters. Correct me if im wrong but it costs 285 for thorn fish, which is +6 damage, that in itself is too cheap compared to the damage you get. Then from then on, its 200 solar for + 6 damage, that is far too cheap.
It costs 225 for +2 damage with leon, 320 for +4 with lonestar yet froggy gets +6 for 200. Something isn't right here. This, combined with stun from splash dash is easy town strategy.
This should be altered so that either thorn fish costs something more along the lines of 400 solar or separate his damage upgrades into 3, still 200 solar. +2 damage each. or just put it back how it was originally.
Voltar is the next character that I think is unbalanced now. He seems redundant now with Yuri's time warp changes, With timewarp he can heal just as good, in a larger radius, slow enemies and make allies fight faster. while all voltar can do is heal and blind enemies. Yuri doesnt even need to upgrade his laser till bubbles maxed out cause flashforward increases its DPS, He's a ridiculously good asset to the team compared to voltar who feels more like a moving target. Id much rather have a bubble Yuri on my team than a Voltar.
To fix this they need to give voltar something else to make him appealing, even just get rid of invert healing wave altogether and just make his heal do damage to enemies as well, no upgrade required, this makes it more appealing to go for straight healing with voltar as you wouldn't be completely defenceless for doing so and could upgrade damage and healing at the same time(Like flashforward, but still not as good). perhaps give healbot an ability that shields teammates within its radius like derpls shield. Just give him something to appear more useful than Yuri!
Coco, I have no issues with apart from her standard attack, the hitbox for it is pathetic, worse than leons. This can easily be fixed by just allowing her to aim freely instead of just left and right. as it is her standard attacks only good for droids and turrets. Other than that she seems solid enough.
Clunks fine as is. Or well, do something about solar bite, it's useless. Make it only 1 upgrade maybe, and make leons magnet piercing give solar too, not just pull it.
Derpl only needs 2 changes, give a radius indicator of nuke and dont allow him to detonate it manually.
Right now the current 'dream team' that never seems to lose for me is Froggy, Yuri, Clunk/Derpl. Pretty much unstoppable.
