Not probably, definitely. Followed by lovely 'whoever has the better upgrade wins' duels.adventures are probably the most imbalanced (and Toxic) part of the game
Oh there are even worse things.. like +3 Deputy/Union guys with 1.5-2k consistently hits where you barely do 500-100 damage while having less Hpsome players have lvl 3 lucile lasso
Sadly almost everything regarding "balance" is wrong with this game, but it's just too obvious with Adventures, and nothing was done for 5 years(?)
At the stage rather keep it that way and deal with Fort Fighting balance first thou. Duels or Adventures won't keep this game alive on their own.
