I think the main problem with the balance changes is pressure from players. FC obviously have to listen to a lot of requests "my keeper sucks in pvp, give keepers more tools!" "I got rooted, nerf roots!" type of biased crap, and most of these requests are from a pvp perspective, in the aim of balancing out all the chars so everyone can fight everyone else fairly in pvp.
I don't think this is the correct approach. If you keep giving more attacks, perks, tools etc to chars to try and even them out, you just create another inbalance elsewhere. Nerf aimed shot and you have a lot of useless agents. Reduce the effect of snares and you completely change the toolset of crats, fixers etc.
I think that FC needs to remember that chars are supposed to be specialists at different roles. Is it wrong that traders are the most powerful pvp profession? Is it wrong that keepers and shades are gimped until the very endgame? I'm not saying no changes need to be made, just that in doing so chars should still be specialised and not make every class an all-round class.
Here are the changes I most care about voicing:
Nelebs rod - Has the same damage as a mortiig beater but 250 less requirements. Almost every under 40 pvp char is using it at the moment. I suggest increasing the requirements to around 450 2hb to match other weapons of it's power.
Traders - 100-174 traders are overpowered at the moment. I think a 150 level lock on nanite drains would be appropriate. Traders have also become a lot more evade based than nano based characters, so I feel that their evade IP skills should be slightly nerfed.
Roots & snares - overpowered. Snares should only reduce runspeed to a minimum of say, 30. Negative runspeed is a joke. As for roots, they should be a maximum of 3 minute duration.
Aimed shot - I think AS is actually underpowered for agents who gain the same advantage from it as fixers, advys etc etc. I think the AS cap should be increased dramatically for agents and replaced with a long attack time, as would be had taking an aimed shot. Shotgun & pistol AS should be somewhat nerfed. I think bow is fine the way it is.
Fixers - from what I've seen fixers can't do their job (running, evading, snaring) better than most other profs at the moment. Runspeed needs to be nerfed for non-fixer classes and especially for adventurers.
And finally, FC should remember that it's okay for a class to dominate pvp, or for a class to be a pvm solo god, or to be a good money-making profession. It's the unique specialisation of the classes I feel that made AO so popular in the first place. Don't make every class into a bread-and-butter combat class, please.
