Hot Rod Chomper is my favorite Chomper (cue the boos, I know), and he looks a bit different from GW to GW2, although both times he looks great, like a shiny motorcycle or something, love it! His ability to gain a speed boost after swallowing a zombie more than makes up for his lower health, as speed is so crucial for a melee focused character.
Unicorn Chomper and Twilight Chomper both change up normal chomper game play to a strong degree if you retain their unique warps (which I do). I pushed the last couple levels I needed out in GW when GW2 launched to get the unicorn in time as I wasn't quite there yet (I was like 303 or something and you need 313 in GW). Interesting to play variants and their warps are similar but still different to each other.
Chester Chomper is fine although I prefer Dr. Chester for these cheesy variants. Extra speed on a chomper is always good when you're playing them and bad when you're a zombie.
Zen Cactus is my favorite GW2 cactus (Jade was my favorite in GW), and even after she got nerfed pretty early on, she's a great character, although you have to avoid the instinct to reload too often as you want to fire that last shot off for the high damage!
I really don't mind the idea of BfN's upgrade system as you can mix and match those upgrades which has massive potential but is lacking due to how it lacks enough good options and instead has too many that aren't that good or considered essential and not many in between. In fact, the idea of massive potential that wasn't fully reached describes BfN in general. If upgrades like this had visual and audio components to make them stand out more, be more obvious to the other team what you're using, and also add to the feel of these upgrades, it would have been much better.
