Best characters in each class, plz share opinion!

My humble suggestions are

Plants

Citron: I just roll out with stock. He has splash damage (5 points per tick) which also adds to the direct hit damage. So you can deal 9-11 points of damage. Party citron as well has splash damage with his laser attack. He's my new favorite class

Cactus: Camo Cactus, but I warn you, you need a lot of practice and the damage upgrade, which is unlocked at Elite lvl3, and you can't fight close range, so you must carefully choose your position and the placement of tallnuts and potato mines ( I played him over 200 hours in GW1, so yeah..)

Sunflower: Metal Petal, you can take far more damage while reviving/healing

Pea: Agent Pea, very high DPS, buffed accuracy from Gw1, just awesome

Chomper: Fire chomper, best DPS by far plus fire damage, although the Unicorn one's warp ability is hilarious to use

Corn: I happen to find a liking to Pops Corn because of his mid-range damage, but he is somewhat tricky to use

Rose: Never ever used her before the patch except the fire variant when I tried to accomplished a crazy Garden Ops Quest, and i wouldn't suggest using her after the patch, but if you really want to be a free kill,probably stock or druid

Zombies

Scientist: Marine Biologist, the close quarter killer since GW1, my second most played character in GW1

Soldier: After the Tank Commander nerf, Scuba Soldier

Al-Star: Wrestling-Star is really good up close if you can hit, and better over range than the default one

Engineer: Sanitation Expert is the best at any range, with good damage, fire rate and accuracy. And toxic damage...

Super Brainz: Electro Brainz, but i haven't used him since the Rose nerf

Imp: Z7, but for non pre-order, S.H.R-Imp is awesome too

Deadbeards: Never use him, since I feel like he's a scaled-down cactus, but Sharkbite is somewhat acceptable (I still kill them 24/7 though)
