Matchmaking/Infamy and Fleeting Up

Assuming two players are at around the same level (XP), and have reasonably even equipment, is there any reason to avoid fleeting up if there's a large discrepancy in their amounts of infamy?

For example, let's say I'm a Mk3 fixer with 900 infamy, and I fleet up with a Mk3 boat in my guild that has 400 infamy. Is there anything other than skill that makes my guild mate a liability in the match?

Thanks!

 

Well skill is a big liability. I would rather play with a mk 3 with 2k infamy than a mk 5 at 1k. But if your guildmate is a decent player who doesn't 1) die in the first 30 seconds or 2) sit back and spam mortars/torps, then there's really no liability.
