Maybe. It would be boring if we could format Pokemon with powers to beat any Pokemon. It would also get boring if there are too many similarly designed Pokemon. However, it would be exciting to make new Pokemon with various strengths, weaknesses, abilities, etc. and design how our Pokemon would look.
Well if you created your pokemon one way it could end up weak or if you created it another way maybe it could end up strong.
But if someone catches on and knows how to make them real strong, yeah it's a bad idea.
Don't argue with idiots because they will drag you down to their level and then beat you with experience.
