Most Wartechers I've seen tend to overlook the power of Range mags when paired with a whip. Shag Hodoog or the Fire Sonichi are your best bet with a whip. If you pair the Guard Crush skill with both then you become a veritable knockdown dervish as the ATA on WT is ok but not stellar.

Anyway, I play a Human WT and its pretty decent in all aspects but compared to everyone else I'm pretty weak. The best thing WT has going for it is that it is great at events due to weapon selection. Same with R missions.

Just remember you will be pretty much the party weaksauce if you are on 360 and that you have to try much harder than almost everyone else to keep your damage up.

(Note, if you play support, go for it- Most Acrotechers today don't bother to buff anyway for some stupid reason)
