Since the change, I haven't had time to do to much xping/raiding, but I have played enough that I can comment on something specific:
I will say that I still view there to still be a problem with low/mid tier paladin grouping with higher tier dps on XP mobs. I am not sure how SKs and Warriors do in this scenario. Maybe this is intended, but it sucks to not be able to preform your primary role when you happen to be grouped with t10+ DPS as a low/mid tier Paladin.
Daffie is currently about T6ish (with a t9-10 2hs), max AA, and working on tomes. No runic2. My only chance to secure agro during XP with high tier players is to use the refuge rain spell. This is not intended for single pulls, and uses to much mana to be sustainable. Additionally, it wont always allow me to keep agro. Monks/wizards seem to be the worst offenders of the DPS I group with, but I rarely group with high tier necros/mages/rangers so I can't comment on them.
Daffie (t6ish) vs. Gegen (t10ish monk) I fight hard for agro when combos are not in use and have no chance to hold agro through a fight when the DPS combo is used. If I do any self healing and/or use an on tier 1hs/shield, I have no shot at holding agro. Daffie does take hits much better than Gegen, so I do want him to hold agro... (This specific example could be a product of the h2h, combo issues, and FD xp loss issues, but the facts about agro remains the same.) I am 100% sure that we could play Gegen less effectively and allow Daffie to keep agro.
I haven't removed my heal spells to replace them with stuns, but that is next on my list of things to try. The idea of losing my heal spells kind of gives me a sad face... I'm feeling like this discourages grouping and certainly makes things not as fun for either the DPS or paladin.
Current spell line up:
DD heal
Self Heal
AE Blind
ST Blind
Flame of Light
AE Stun
Rain
