Again this is not a thread demanding at this stage is a open discussion on what people think about it.
Basically more and more I've just found myself annoyed when a ppu shows up as it means either the enemy or my allies will be getting buffs and just be far to much for the enemy to handle making the fighting boring. Yes sometimes the enemy is awful and you can overcome the ppu but generally this isn't the case, and even if you kill a few of them unless the ppu is also awful they will get a rezz.
All the ppu does in my eyes is make pvp more annoying when they show up as fights last a ridiculously long amount of time, they become unfair most of the time, and you can end up being dependent on how good your ppu is as if the enemy ppu is hitting every anti buff and heal while yours isn't then you've lost the fight through no fault of your own (again assuming equal skill level between you and the person you were fighting).
As I'm sure people realise most of this is based around fighting in pp1, OP would be a different kettle of fish and could perhaps require a rework if they did this (OP fights indeed as I type this I realise are the main issue against it unless people can think up reasons to the contrary). One solution would be to make it so when attacking the OP first of all you need to (or can) hack the GR which gives you're clan or allies the ability to GR to it for say and hour so if people die they can return quickly. This would not only solve the problem of fights ending very quickly if people slowly die but also add a whole new element of OP fighting as you would need to have a poker there and keep the GR room safe. They could also make it so you get less SI when you GR to a GR that has been hacked by your clan/faction/allies.
Of course this would also mean pve would need a rework (which is does anyway) as right now you cannot pve without a ppu apart from by exploiting however this if anything would also be a good thing as it limits the ability to get essential gear like rares to those who either know the exploits or have a clan to help them.
Finally the apu could be given the rezz and a lower level heal, the heal because right now I believe the apu has no way to self heal so removing the ppu would mean they would need some kind of self heal even if it is only a minor one in the same vane as the heal other people have, one to heal after a fight but not to much use in it. As for the rezz, thats more of an idea as rezzing is the only handy thing the ppu has I would hate to loose as it makes dueling without NF possible and is also useful for pve, that said though it might also end up making the apu the essential character for pve as well.
Well those are my thoughts and ideas, feel free to show support, alter ideas, or shoot them down as you will.
Edit: Additional idea, instead of removing the ppu they could alter is so their buffs are only 50% effective against players (or perhaps less) this way ppus would have a place in pvp but not the huge place they have right now being basically equal to another 2 or 3 people joining the fight.
