Why even give a **** about T5? First 4 T6 bosses are designed to be doable for T4 geared players (Cirith said so earlier this year), after killing 4 bosses, players should have some t6 gear for the last two.
Anyway. I only got 5 T5 pieces which will turn useless, so I guess i go back to my T4 set. T5 hat looks cool though for vanity slot.
Ps. If something doesn't happen very soon, then I am afraid another guild is about to fall (Old guild, so sad).
