Level differences in IB barely make a difference. Did about a 2 hour run yesterday and got rekt in one round but went with a 2.25 KD ratio on the next matches. Titan level 30 in IB cuz I need the gloves. The only time I felt a noticeable difference was with a 3 or more level difference. This level 27 guy got the jump on me and I thought I was dead but he barely dented me so I turned around and shredded him. But against level 29 and 31 guys it's fair game. If you're 3 levels or more below 32 you shouldn't be doing IB but at low 30 it really isn't that hard.
