Enchanters from beta (or devs) ~ a few questions.

[Zapp Brannigan]

Due to the long coming grind (which I enjoy, dont get me wrong) I have a few questions before I spend the next month investing in my character only to be really dissapointed

1. How much is the 50% pet dmg solo rule going to effect me since post 20(?) I'm guessing its going to be very difficult to even reach 50% dmg with spells as a enchanter.(and forced to use the stupid work around)

2. How did charm work in PvP on p99 red during beta? I did read it was op then nerfed to its current state on blue p99. Are there plans to A) keep it the way it is B) follow blues 99 timeline of OP/nerfed C) not known?

3. If I charm mobs for pets, tank target down to 10%, then break charm, root/mezz pet or re-charm: does it avoid the 50% pet dmg rule?

~thnks, did search/google for answeres but there was only a single off comment from a dev about these questions.
