For the orb to be effective, you need to be able to buff and opponent should not be able to target you. You should not be able to be stunned, rooted, iced, beckoned etc.

I like that it works on revive also as long as you can buff and not be targeted so you have a chance to survive.

Many ppl are forgetting that spawning can happen in PVP maps as well as CTF maps so the orb is needed in both. I understand a lot of ppl only play forest fight but it is not the only PVP map that exists.

I don't think that damage should be reduced. Armor needs to be increased and it will benefit both PVP and PVE.
