Jarkko, please, try to hear what others are trying to tell before judging. Consider following scenario: you are going to storm a castle of another player in late game with all 9th in research. There are some 20-30 mages inside and tons of summons and whatnot. You have something on the same lines. You have a good battle plan involving playing on other player's race weaknesses: for example, he's vulnerable to cold, or fire, or whatever. He has the same against you. Now, you both need gems to realise your plan. You surely want to cast antimagic, some Army of, perhaps Mass regen etc. He too.
Now, castle storming goes after the magic phase. So he casts 3-5*GR on this castle. Your troops are perfectly capable of destroying all the horses in 10 turns without any magic at all. Still, your mages start casting all scripted spells and after that there are several possibilities: if you gave them just enough gems for their script (usual practice to stop AI from crazy things) you storm the castle without gems and lose. If you gave them many gems, they start doing crazy things and spend all their gems and storm and lose. If you gave them really many gems so they still have them after GRs are killed and the things they were doing were not crazy enough to kill them or your army, you finally have some chance to actually storm the castle, not taking into account that the opponent will be able to use much more gems in the battle.
And you have absolutely no way to do anythinng about it.
Have you experienced it, Jarkko?
