I was look on the main sit eand i saw at rewards from pvp ..trebuchet and siege weapons ..hmm is this a joke ?!

We need some good rewards like ranks/pvp weapons (swords axes) and pvp armors etc .. I was think we can grow in skills/levels in pvp and get some gear and weapons as rewards.

All of what you said will also be there, but the trebuchet and siege weapons are for the siege warfare. This isn't battlegrounds and arenas, bro, this is a battlefield with keeps and villages and stuff. You'll need the trebs and ballistas and stuff to break down gates and walls so you can get past the hard chocolate shell and to the creamy nouget center (the enemies).

There will not be different stats for pvp though. You may get weapons and armour through pvp but you can use them in pve as well as pvp.

I see ..well im ok if there wont be pvp specific items but i think there should be some rewards (as weapons and armors) from doin pvp activities ..because i may go only for small scale skirmishez and i wont use balista and catapults of any sort .. so if i am doing pvp and not pve i will need to get my gear from somwhere in the pvp area..

i am sure the pvp weapons will have unique skins and i think they have already said that there will be ranks/achievments

You can definitely get gear from PvP, likely with some PvP related set bonuses, but there's no "PvP power/resilience" type stuff.

I believe they have said Alliance Points (earned PvP currency) can be used to purchase gear in PvP.

Yep, among other things such as siege weapons and the like.

very nice to hear ...
