Turning my near maxed Mauler to a Zerk?

What's going on guys?
Was staking yesterday and ended up getting 2 defence while switching my attack styles and at this point I've just been thinking about going zerker. My stats are:
50 Atk
90 Str
89 HP
99 Mage
95 Range
2 Def
31 Pray

Should I go zerk? And if so, what quests should I do for my defence?

 

2 defence isn't that bad!

You most likely didn't even get a combat level through that...

if you really hate yourself for 2 defence and really want to go zerk tho here's a guide for you http://forums.zybez.net/topic/1574534-ultimate-rune-pure-guide-trainingquestsitems/
But if you get defence, why not try 20 def? Just do nature spirit and what lies below for the def quests.

 

2 defence is nothing to fuss over, if you really want to train defence then go for 20 defence before you go 45, you might end up liking 20 defence, I know it's one of my favourites.
