The thing is back then paladins had good agro. Since then, the class has been nerfed bigtime which is why we are all talking here without the input from GMs.
to my knowledge paladin aggro hasn't been nerfed since the heal nerf which iirc occured in 2007, in fact bash aggro was buffed a huge amount somewhere along the way. correct me if i'm wrong
i've played all 3 tanks for a lot of tomes worth of exp, and i've never really run into this class breaking aggro problem. if aggro is a big problem, you can spam stuns for ~700 aggro, and maximize blinding and bashing to optimize your aggro. i spent years raiding with bango as the main tank and these serious aggro problems just didn't really exist except on high MR bosses. post runic2 change, aggro wasn't even a thought anymore. i actually prefer playing paladin of all the tanks, i played a lot of vartenaal and more recently bango. they are a class that really excels with skill, and is an active and fun class to play. they are also tremendously powerful healers in certain situations, especially in 6 mans, and bring added utility of potl, piety, loh.
sure you can't keep super high aggro on a boss while offtanking multiple mobs, warriors can't either without AE taunt, but i would gladly accept the challenge. blind each offtank mob once, assuming they aren't being dpsed, then you can weave in triple blinds on the main boss + also hit it with ae stun. monks can feign to drop aggro if the tank dies, rogues could potentially be a problem but smart ones can escape, ranged already have 30% less aggro simply by virtue of being out of melee range. i've seen many times on hard bosses like custodian and blazewind where stryda or jraul or whoever dies and bango successfully picks it up and we kill the boss, unless he's using conduit (another awesome ability).
i'm not saying i wouldn't like to see them buffed. i really like the idea of group hot giving a veil-like effect, or some other change allowing them to be able to utilize their heals more often. i think it's only fair seeing as the massive buffs SKs and warriors have gotten, but paladins are entirely viable right now. i think poor play and public stigma is the main thing holding them back. the paladin community has way overplayed their plight which I think is the main reason devs are afraid to touch the subject any more.
