Thing needs a buff

Only winning about 15% of games even with tking. Could just be noob things, because when I and others in channel play thing its very easy to win. But would love to see 1 of the 2 buffs added to thing

1) Crawl on the walls (maybe with a long cooldown, huge energy cost, but jump from 1 room to the next crawling over walls)

2) Infect dead bodies, giving them the infested marine model for 1 minute or so in which time they are transforming (this was in movie, took a minute for thing to full resemble human). If they are not killed in this time they become minithings.

I may add the cliffs buff, I'm now confident on how to work that out.

Wouldn't crawling over the walls kinda negate the purpose of locking doors

Honestly I don't think the thing needs a buff at all. If your gonna buff it the marines may need a slight buff of their own. I have been winning every game as the thing by killing doors leaving me a clear escape path and then baiting the marines through a door locking it, cutting them in half.
I don't even bother trying to be in their group mostly because of random tking and how boring it is waiting for a chance to kill someone and having them run away, when I can just kill doors so that doesn't happen. The only time I have lost recently is, because one marine was smart enough to wait for me on the other side of the door while the group moved up on me and he locked it. Most people are just really bad at being the thing. Me and solid even 2v1'd one thing because he was so bad at it. If he's gonna crawl walls I don't think he should be able to use it to get to the other side or that would nerf the lock ability and pretty sure that would make it impossible for marines to win unless they never split up the whole game and perhaps killed the doors themselves.
