1. Don't 1v1 against classes that have advantage in 1v1. The class balance was calibrated with team roles in mind so there are classes that excel in 1v1 but are balanced in 3v3 or more.
2. If you can't beat them, join them. Try playing as a cra or eca. That might improve your chances. At the very least, you'd discover their weakness.
If I had people to play 3v3 kolo with, I would. I tried the solo 3v3 and people in there are very toxic. I am not paying for a class change, fights need to be better balanced.
Level 200 hupper can't reach a cra? I'd suggest you focus on 3v3. Cra isn't broken just very annoying on big maps. Eliotrope is probably the most annoying on big maps though. As a hupper you should focus on getting in close early and locking the cra. Hupper has plenty of tools to do that. Changing maps affects all classes. It's a bit shortsighted to affect everyone for your lack of experience, no offense meant.
P.S: If you are needing more direct advice, use creation and journey vs cra.
You cannot use creation until you hit the enemy. Journey only gets you 5 tiles and 3 turn cool down. It takes 3 turns on the big map just to hit a Cra once with techtonic breach. You cannot reach him with anything else. Most Cras by the 3rd turn will have you under 1000hp.
