First of all props for using proper English grammar and spelling ... it's a rarity on here.
I disagree that point #1 faction imbalance was a problem and I believe that faction specific titles made it worse. While it was somewhat tough finding people ro play with on horde last expansion it wasn't nearly as bad as finding anyone on either faction this xpac.
#2 - human racial is (at least for priest) even more important - while I agree that racials in general are much less significant than in WoD, human racial is an exception (because gameplay is 99% faceroll pve rotation zerg damage with kills in stun and having an extra stun breaker is huge).
#3 might look better on paper but in practice I have to grind for weeks on end to get my vital pvp talents and that doesnt even factor in 3rd relic slot and artifact level. in wod i had to spend 2-5h in ashran to get my basic pvp set and i would be competitive (at least being able to have fun in aemi high rated arenas while getting my conquest set).
so yeah the new system is MUCH worse for entry into pvp unless you consider doing BGs and just spamming your pve rotation 'fun' - any serious pvp - entry level or not - is awful if you're not allowed to pick your talents freely.
