I only need 1 midget tank. Blizz is superior to Treek.
On my PT, I only need one tank- ME!
I stopped using Mako because the I didn't loose enough health per fight. Tanking is too easy that way. Now i use tEl Diable(Gault) or SquishyMando(Torian). May have to try Blizz as my off-spec because AP-tank-stance is dead. he's not very well geared, though, and I don't want to put my offspec gear on him.
On my Lethality Op, I use Temple, just because i can heal myself and get a TA off it, and RDPS+MDPS=Melted face
