I don't often comment on this stuff, but this is turning into the same complaint style as we have seen with Evard's Tentacles time and again. The perk is fine as it is. It really shouldn't affect pvp so much, especially with the recent adjustment, because the invis still breaks as per normally with open attacks. Its no different than fighting a wizard who casts invis on himself, except the sorcerer in question (might) be free from taking another action to reapply by casting. If you don't have the ability/potion/spell/whatever to see invisible creatures, then you'd be screwed either way.

Now, as far as the RP aspect of it, you should be creative enough to roleplay your situation, and it should fit into your concept/story, etc. If you don't think you have the stuff to pull that off, then you should probably consider something else.

PS - This is coming from someone who hasn't even reached the level of perma invis, and tbh, mechanically it'll be a small convenience at best. Nor will it very much change the way I'm already playing the concept, except to act as a progression to the STORY.
