Honestly without actually seeing your character and how he rps it's difficult to offer any help with this, from the way you have described the situation it could genuinely be a problem with the character itself or it may just be an issue of how you could be pulling him off, it may be both.Â
Depending on what the problem actually is there are some wildly different solutions to addressing it and without actually seeing how your character plays I'm afraid there's not much I can give you beyond(if you can) stepping back and using a different character to see if you get the same complaints. If you do it might be just a situation of stepping back and letting someone else take the wheel. If it's a character issue you may be better served finding some rp reason to adjust his echo so others don't feel he can just mimic their ability and make their contribution seem less.
