There seems to be rather heated debate on US forums over how viable is the hybrid for group pvp.
Jcp23 did a SOLID POST about hybrid vs xxx/general specc so if you don't want to cut through 2 pages of crap such as "hybrid rules, and you suck" jump straight to his post.
I have to agree that in 1v1 lotus specc HAS NOTHING on Hybrid, and if hybrid sin opens with FTD and uses shard for avatar it is all over but the crying, baby.
Same goes for HOXes, its very very hard for Lotusins to kill them, where Hybrid just jumps in and outheals the poor bastard while using avatar.
I remember that I had to work my ASS off on test server to beat HOX in fair 1v1 as Lotus (did 1-5), but hybrid got me 5-2 score without much sweat.
