What class/vehicle do you have the most certs in, and why?

[Assist]

I'm curious what you guys have dumped your certs into since release. I recently rolled a TR character and have realized there's not as many things in the game that I think is 'needed'. But then I look at my VS br100 and realize how many dumb things I have put certs into over the past months. I was talking to my co-worker, whose BR 35ish, about what to spend certs on and it's just weird to think about buying new weapons with station cash rather than certs. So I looked on the Planetside 2 Players site and saw that BR35ish is only around 6,000+ certs, whereas a BR100 is 84,000+ certs.

Just doing some quick math, I think I actually have more certs into my Galaxy than any other vehicle or class. (For some reason I thought having a fully certed Galaxy was a good idea). Between the 4 guns, the Galaxy itself, and then acquisition time I think it adds up to the most of any class I have put certs into.

I'm wondering though what you guys have your certs in, what do you wish you had/hadn't put certs into(Skyguard), and if I'm the only one out there who tries to keep a reserve a certs for new weapons that could come out..
