I think the worst thing is it being 2 defence, I've accidentally gotten 2 defence on 2 different accounts, and the fact of it being 2 defence has made me train it in the end, if you can handle it being 2 though, then it won't make a difference at all
exact same thing happened to me while i was doing horror from the deep, it doesnt make a difference in pking but if you stake it kind of makes a pretty big difference (it replaces hp)
Well i'm a protectionist so I would start over because I hate looking at 2 defence aha. But really its no big deal just keep going unless you're like me.
I had 2 def on my first pure, couldn't stand it and went range tank. I personally made a new account with 1 def, but it's all up to you and if you can stand looking at it
