Elemental Staves & Wands Known Issue

Isn't this how most MMORPGs work?
Your current equips will either be obsolete once expansions come in, or you'll have to upgrade it by ridiculous amounts to keep up.
Even games like WoW work by adding bigger and badder equipment to make older ones obsolete.

You are absolutely right. The good chunk of people that constantly speak about endgame, perfecting a piece of gear without any grasp of this must be born upside down and inside out or something. If you fail to understand that endgame is relative and never future proof, you do not deserve to be a top tier player in any game. That said, there is a certain difference between an item going out of fashion because better stuff comes along and an item being nerfed.
