These are 2 that really suffered being brought over to BfN. I love Loudmouth bot in GW2 in the right spots (preferably near the objective but being at least partially protected by terrain), and goop shroom has been a great help since GW1.
A small side note; in GW2 you'll get the quest 'vanquish 7 gooped zombies' and while the best way to do that is to jump on a Chomper, you can use goop shrooms and play as any plant class and get credit! Actually you can also have a chomper friend goop them while you vanquish them as well.
When they first made goop grody goop in BfN, I was actually looking forward to using it more as Chomper is my least favorite class, partly due to how it's abilities are largely 'selfish' but it went from being largely ineffective to being too good in a single patch. The potted plant matters less as they tend to have open spots and can be sniped easily from far behind their own range.
@Iron_Guard8Loudmouth bot was the perfect ambush bot and it was fun waiting for careless players to walk into the trap in gw2.
I never thought about the goop quests! Thanks goop shroom.
Goop and chomper is a controversial subject. I prefer gw chomper in the idea but he suffers a lot of the same problems as the spy. A unique idea of a class held back by his own players in a way and buggy hitboxes (suicide chomper and kamilaze spies). He really would've benefited from the back chomp rework as imo playing chomper as a sneaky support class in gw is the most fun and effective way to play and it's why hot rod and vampire chomper are so popular do to their survivability.
I remember how badly grody goop went from the rather meh it tickles ability to an objective wiper in a patch.
Chomper in bfn feels like they tried to make him more viable but made a lot of the mistakes that drag him down like his stupidly powerful ranged attack and spikeweeds that deal 100 damage and get shot out but ultimately fail due to the absolutely awful areas to put them in bfn since they stick out like a sore thumb in the light. A reward for surviving swallowing in the game where he only has 1 swallow attack that easily gets rid of armored enemies (gw1 chomper just ignored armor when chomping). He's also the first character to be so broken that they had to remove him lol. Not to mention his swallow animations in bfn are kinda weak: gw all star: halfway inside chompers mouth, can't survive. Bfn all star: bro just jump you'll make it.
