Best trinket for rogue pvp?

Tsunami
dragonspine
bloodlust brooch
battlemasters
warp spring coil?

Going to get a new trinket for my rogue. Which one is the optimal choice for arena?

Thanks!

2 glaives + DST best choice :)

Bloodlust Brooch is your #1 here because it's the only one you can control, has flat AtP and AtP on use, and that is what you should be looking for.
As a Rogue, you'll end up more of a timing and controlling things instead of just pulling max dps, that's why other trinkets you mentioned are more PvE oriented.

With Zul'Aman right behind the doors, you'll be looking for Berserker's Call.

/Edit: If you're jewelcrafter, you can make your panther trinket, it also increases your stealth level. It has to be said that it's use ''spawn'' little panther following you during trinket's use duration who's not going to stealth when you does. It can be abused by high rated players and turn against you.

Like it matters? a 1 year old could play Rogue to 2k rating in TBC.
