i think the bw warlord is a strong mage. not top shelf, but certainly not the bottom as you suggest.
Seriously. What can I do to convince you, that BW Warlord is the weakest mage (together with Siren)?
I am not even sure, if the Warlord CAN win at all against druid/necro/priestess, even with enormous luck and constantly rolling above average.
Well, I am online on OCTGN and if I lose 1 out of 5 matches with tier1 against tier3 I might reconsider my position. But honestly, I don't see it happening. The tier1 advantage really exists, it's not something I made up to be edgy in a forum.
/edit: Keejchen, Powlich, Jack.. if you read this.. you know what to do (if you don't agree with my assessment :p)
