I agree with you that melee are kind of weak at the moment in PvP. I feel like they need to increase their movespeed or give them a 20s off GCD heavy skill or something for PvP useable by all melee classes.

The strongest comp out there right now is definitely Tank, SMN, BLM, Healer though in my opinion. The healer/tank is interchangeable but in my matches that one is the hardest to figure out your priorities. It does have its counters though.

I like PvP in this game because there is a counter to almost every strat. There are some that are stronger than others by far though melee's definitely need some attention. I don't necessarily agree with summoners being "OP" though. The only way they can kill someone is if you ignore them. If you ignore any class they will kill you eventually though. IT comes down to how good the people you are playing with are and if your team can think on their feet. If you solo queue/do 3's though I guess that element of PvP is lost.

But in the end I play SMN so most scrubs on this forum won't really have a conversation with me until next month when the next FOTM class is decided.
