After finally playing a decent amount of games at a decentish mmr 2400-2450, I can say paladins are better than I had first expected. I feel with the Saved by the Light talent and glyph of freedom we are actually very very hard to kill. I have been running PHD and WLP and can say with rotating Saved by the Light and Deterences and using freedom on me every time I am about to get cced, I have a pretty easy time keeping my team up long enough for kills. The exception being vs LSD 2 and sometimes RLS when rogue is running deadly throw interrupt. One thing I have noticed is that I feel glyph of denounce is very very strong, I use it vs every team. Being able to gain an extra 17-20% crit is huge in keeping your team up, you must keep this buff up constantly. Last but not least, if I know a team will be training me, which is pretty obvious nowadays, dk/rogue, rogue/hunt, ret/dk etc. I will drop beacon of light glyph and run Divine Protection/Freedom/Denounce. This because I won't be needing to constantly swap beacon, and allows me to keep all of these very strong glyphs. (Remember Denounce is very very strong vs cleave and is imperative in making sure the enemy team does less damage and making sure you do more healing.
Yeah, was looking at Jimjim's gear setup, very interesting and I remember throughout MoP you always had ran full haste/crit with very little spirit. I think Pursuit of Justice is actually better currently due to the fact we are holding on to our holy power much longer. In regards to mana, even with spirit pieces when I go oom I have no regen other than getting a drink off, so I think Jimjim's Haste/Versatility build might currently be the best.
To be completely honest with you, I think our utility is great since we provide great mobility, and we are tankier than most healers in this meta of killing the healer all game. I just feel that our heals are very weak, it takes me a bit of time to top someone off with with an MS up. I think this could be a problem since most of our heals need to be casted now and our instant heals seem lacking. I have played a bit of skirmishes and the biggest problem is dealing with teams with double lockouts. Mage/lock, boomkin/dk etc. I just feel that I have to fake cast and then juke myself to death. Whereas druid and priest can keep up with instants and absorbs. I think pallies are currently middle of the pack, and maybe with some more crit will feel a bit more strong.
