do i stick to my old terran biological ways
or do i switch to zerg scum?

If I was on the same level with both zerg and terran, I'd choose terran.

Terran if you wanna die to Protoss
Zerg if you wanna die to Terran
Protoss if you wanna die to Zerg

"balance"

Zerg is pretty sweet in hots, I always loved ling/infestor/ultra play and ultras are strong as fuck now
roach/hydra is pretty decent its much better than roach/infestor bullshit
They don't HAVE to turtle as much anymore like they did in WOL with bl/infestor but majority of Zerg players still stick to their roots of being absolute cunts and use swarmhost/spine/spore/viper/queen/etc slow death push

ZvZ isn't a muta war anymore since spore cannon buffs

If you liked Terran Bio, you will enjoy Terran in HotS...

obv protoss

Stay as terran.

Don't be a bitch.

This is so true lol.

i went from toss armada multiplayer wol, to urly swarmhosts in hots
locust free unit, +40%speed on creep, 68range (4.5 times more as tempest)
