The changes recently done in PvP are clearly for enhance the competitive part of it, and frankly the "exp" part have no sense there, I'm going bold and think it is best have "exp" being removed in toto, to lessen the problem of bots or inactive players there just for the free exp.

The game have so much options for fast exp that removing the pvp option is not a big deal.

Wanna exp fast? Go POTD.

There are limits if you want keep as solo player.

When you reach the raiding part of the game you'll be faced with reality: when solo you can do pretty nothing because...
- The raid finder groups are 99,9% requiring the clear already done;
- The "learning" groups (when any, as they are quite rare, at least in my datacenter) are a bunch o' people that dies even in telegraphs and joined raid only because tomes gear let 'em unlock it and last but not least, the group will ragedisband at first wipe (...);
