Marine Biologist vs Plants

First of all, Scientist is NOT a support class. The developers once stated that he's supposed to place down a heal station, warp in close range a destroy the plants, taking their focus away from the garden, in order to enable him to deal massive damage to the defenders, especially the Cactus, which he's supposed to counter. Kinda like the Scout from TF2. And the damage profile is only 50 (52 with the upgrade) points, even if you stuff the gun down their throat. I'm not trying to be rude, but this time, you're telling a bit of nonsense. Or you're just going for the funny 420-reference. However, I agree that it's far easier to hit the full damage blast than in GW1. But their are easy ways to counter him. Peashooter. Hyper and abuse your splash damage. Citron, EMPeach him, when he regains control, use your shield to tank 1 1nd 1/2 blast from his gun and finish him. I suggest you use Citron if Scientist annoy you, he's by far their best counter. Chomper: Fire Chomper, 'nuff said. Corn, use Hosk Hup if you see a Scientist warps towards you, it will shred him. Sunflower isn't supposed to enter close ranged gunfights without help anyway, but you can find a Citron to be your bodyguard. Cactus has Potato Mines, place them around corners, even experienced Scientist mains fall for the seemingly easy kill  (including me). Rose, use your Arcane Enigma to deal between 60 and 80 points of damage, the goatify him. Doesn't work all the time, but if you pull it of, it's pretty damn embarrassing for the Scientist.
