Definitely learnt from their last world event. I just got the Armadyl boots and gloves and decided to switch sides to Bandos so I can begin to get some of that warpriest gear, and you can only reclaim it, which I'm going to assume means you can't own both warpriest sets this time around. You could also get placeholders of the first world events warpriest armour by switching sides and then switching back (but having to buy them back at full renown), again, it's only a reclaim option. Sigh, I'm fed up of not being able to have placeholders for the majority of my bank :( especially when I'm willing to go to extra efforts to get it. I know they stated it in the release article but I was hoping there would be some work arounds, guess I'll have to wait for the event to end to claim the bandos gear from the GWD maybe? Anyway, if you are all wanting the cosmetic over rides, you'll be best off starting on the side you don't want to win/support so that you don't waste a crap ton of renown!
