You shouldn't use the full set of relic full time ever. The only piece even worth wearing more than just <wait 1> lengths of time is the hands and even they are greatly outclassed now.

If your really concerned with a "counterstance set," you should pour on acc to reach cap first and foremost.

Your standard tp gear should also double for your best counter gear, you will do more damage by far.

Level 50 weapons tend to suck when compared to level 90 weapons, and we will continue to ignore +counter on weapons when the weapon isn't as good as the next weapon over.
