The only way to fix teleport is to remove it completely from combat. However, teleport is part of nearly every combo and creative solution. Creative gameplay is what the game is about, that's why teleport with its current 2 AP cost will never be touched now. The game will just give the enemy a "Grounded" stat instead so you can't teleport them out.

High ini battle is going to be a balance nightmare anyway. What will you do about 4 ranger comp stomping tactician with 4 arrow storm? Oh, nerf arrow storm. Then I move to meteor shower. Nerf meteor shower. Then I move to Hail storm. Nerf hail storm. It goes on and on and on. It has more bad than good. They will have to add fog of war into the game to prevent turn 1 stomp and let's not have that. Fog of war is on so many people shitlist already.

@kalrakh : And the build you mentioned just show that people will just build to remove the RNG and maximize their chance.

It's like making our base hit chance starts at 80 instead of 95 and it goes up by +1 per fin for melee and +1 for wit. Suddenly, everyone warrior will have Fin and every ranger will max wit real fast just to land the hit all the time nad make the plan more consistent.
