Grab up items you want now!

I wouldn't buy anything with special attacks since they're taking those out for combat buffs.

Keep in mind that there will be class specific abilities, so if all claw types have a certain ability that is decent (which I assume it will be) then obviously you'd want the best weapon in the class to use, which is dragon claws.

I had not thought about it in that sense, you're right. I imagine they'll still be in demand and worth their weight. I was just thinking about all the people who may or may not flip their lids when they find the special bar has been removed on their beloved Armadyl Godsword. I gave godswords more thought than anything else because Jagex mentioned the four godswords will essentially be the same weapon and their only difference after the update will be purely cosmetic.
