well i assumed super climb removed hate from wyvern as super jump did the dragoon, either way, when u see an AOE coming u could make the wyvern super climb on its own if it were a pet command and he would be out of range (in the air) while the AOE went off (as i've done with super jump many times). I believe thats what Byxfluzba meant. although this may or may not dodge one AOE depending on your timing. I think this wouldnt be nearly enough help for the "Keeping wyvern alive during AOE spam on NM's" problem. the wyv simply needs to be tougher in some way.
surely super climb removes hate...because when u come back down neither u or your wyvern has hate. You have to turn and let your wyvern hit it before he has hate.
