The disappearance of strength polearms has been much lamented over the course of the past year, with not just one, but two questions in The Queue, WoW Insider's daily Q&A column, asking whether they will ever return. Ghostcrawler recently answered that question:
@albindahlander It's on the list, but unlikely before 5.2. Sorry.- Greg Street (@Ghostcrawler) February 9, 2013
A light at the end of the tunnel appears! The problem with polearms, for those who weren't aware, is that they have a different animation to other two-handed weapons. Their set of animations includes a sort of poking motion, as well as the usual swinging and overhead smashing. This is the reason why they can't be transmogrified into other two-handed weapons when transmog restrictions are relaxed with patch 5.2.
This different animation issue also rears its ugly head when it comes to Titan's Grip -- the fury warrior dual-wield ability. There is no dual-wield animation for polearms, so warriors currently can't dual-wield them. This has likely been what's preventing Blizzard using them as end-game weapons, but Ghostcrawler's tweet heralds their return. There is already a strength polearm in the patch 5.2 loot table, as the tweeter says, so hopefully Blizzard will sort a fix for the dual-wield issue sooner rather than later.
