To: The_Saurus. PvP opponents are always given on Keeper level. If you want to have a chance at all, try leveling up your heroes as high as possible. Give them the best equipment available and the most efficient skills, and use the Soul Skill of your heroes wisely! All of this makes the difference between victory or defeat.
I don't know what guys saying "pay to win" expect from the game. It's all fun to see the enemy die in PvE. Why bother to gain a top rank in PvP? It's pure virtual, isn't it? Really want to pay for that?
Re: you are too weak
p: player
e: enemy
h: hit points
a: attack
d: defense
If p.h - (e.h / (p.a - e.d)) * (e.a - p.d) <= 0 the player is too weak.
Tip: Try SAGA Dungeon or Enchanted Cave. They make use of the same formula.
8 Heroes, with multiple portraits, and without any memorizable names - that's neither epic nor heroic, that's just slightly above the noname universal soldier. What a pity!
