Yes a Colonel time can really ruin your experience - and i apologise as well.
There are mostly 2 reasons why a colonel is going to be kicked in the most cases :
1. your allies that are a bit higher know you can just use r3 weapons..which is not that pwerful.
2. your allies dont know you yet, means they dont how you play yet
For that is a easy solution - you have to make your own rooms, and show off what you can do. Allies will recognize you and instead of ,,Meh..a Colonel'' there will be ,,Oh yeah its him!''.
And you will not just gain respect on your allies side, if you're in team with chariots and perimeters without going to be kicked - then the enemies knows that you're a pretty badass.
And also as well a guild is a cool solution, you can play together - have fun and chill
