well i just start playing retail so i'm nooby...can u explaine what u mean pls? :)
i mean i understand that when u have OL u don't rly need WC,but SE?...
It's not a terrible set-up but an OL is an okay substitute for a WC if you have an SE in the group. The SE makes it more bearable. If you had an EE is than slot, it wouldn't be that good. In the coming updates the OL get's some new buffs that make it a decent replacement (attack speed buff or rather 'Haste').
There are some key buffs that you miss by not having a WC though like War Chant/Earth Chant (offensive/defensive buffs), and your choice of Prophecies (high level mega-buffs that last 5 minutes) isn't as strong as it could be.
Thinking about it more though having a WC anyway and an OL in the party in place of another DD isn't a bad idea at all (in a 9 man group, you'd have 4 DD's normally). In your case you'd have 3 DD's and the OL. With the coming changes to the de-buff system, it could make your group pretty strong in PvP... When you get there anyway.
WL (AoE DD), Ber (DD/Pulls), OL (AoE Debuffer), SE (Recharges/PoWi), WC (Main Buffer), Bish (Heals), SWS & BD sounds good
and get another pole class since you only listed 8 ppl. in the next update the Berserker will have his poling abilities nerfed so grab another WL or a Titan, or even a Warsmith that could do your parties crafting ;)
MAYBE a tank for single target PvE x.x or Raids, depends what you want to accomplish with this constant, you could subclass alot of this for different situations if your planning for the long haul.
