Square certainly never promised that this would be the PvP patch and nothing was ever said about new PvP armor, materia, ranks, or a changing of GC restrictions. I understand why you want these things, I want most of them too, but you can't hold SE to promises they never made.
As for the roulette rewards, I was bummed to see that there were no PvP bonuses either, but what it does have is enough to encourage new people to participate. 100 sol and 40 poetics for one match might be a big enough draw to bring in players new to PvP.
As for healers in PvP...I find slaughter much, much more enjoyable as a healer compared to Secure. Because of the amount of players at mid I think it's harder for healers to be identified and focused down, which means it's easier to go about healing without being constantly inturupted.
All and all, I think this patch has been amazing for PvP. I've had a lot of fun with the new mode, particularly on my healer.
