I mostly like new PvP but I probably need tips

[DeMarcy]

HEy guys, a have a few questions to talk about:

First of all - im switched from Chaos - to Aether so im new here and want to say hello to all pvp-player.
Im sort of "Content-Player" which means that I play the old contents through and therefore im at Patch 2.2. (I know its very old)
So at the moment I tried to clean up my inventory and did find "Ikarus-wings".
So are for FRONT and give you 300 TP.
But with 4.0 PVP gets completely changed and now my Paladin just have 1 skill which use 300 TP: Shield Bash
So I'm wondering - could it be that the wings did get useless?

Maybe you can help me and discuss this case with me: I think there sort of other PVP-Items who match this.
Greetings
