'How about a pokemon cannot evolve mid battle until it has a knock out?'
(fuck the anime seriously rofl kingler v exeggutor before xscissor existed)
Well, even if you evolved mid-battle, you're supposed to get that 1 EC. Somehow, I recall something from someone stating that mid-battle evolvers are using that very EC. Which means, you have, say, 5/6 EC on Riolu, you release it, it automatically gains the battle counters, and use that 1 EC to evolve immediately instead of waiting for the battle to resolve. So if you evolve mid-battle, it's a definite that you're claiming the EC outright, instead of what may be an FE mons 3 MC.... With that last part, i mean that if a pokemon has 5/6 EC and evolves mid-battle, he will still get 1 EC at the battle's rewards. That prevents mid-battle evolutions to be used as a free evolution counter (And Move Counter, if the pokemon became a FE with an unlocked DW Ability), which seems to be a big issue regarding this.
On a side note, how do we feel about unlock DW Ability upon release or during the battle?
