Conditions and hexes aren't that great VS abbadon himself, and the monoliths have no flesh. Abby has resistance so all conditions are like half duration or less and the degen doesn't do much to dent his HP. This can work to your advantage with Wastrel's Worry though, you can spam it through the daze(or order a hero to do so). If I was a ranger I'd take a hard hitting spiky type bar, Glass Arrows or another + damage prep with Tripple Shot>Penetrating Shot>Sundering Shot>Savage Shot/punishing shot, then Body shot/dual shot>penetrate>sunder>Savage/punish, on a hornbow(the last 3 attacks recharge in sync, and you can alternate between trip shot and body shot for if you need energy, basically every 5 seconds you launch 4-6 arrows at something and it dies or gets hurt). Put on the lightbringer title and just spike stuff out, interrupt torment claws ect. The energy gets tight(even at 14 expertise, everything costs 4 energy), but you can swap in a zealous weapon, or take some ritualist or paragon energy support skills.
In fact a rit hero or paragon hero is pretty badass here, there are rit item spells that kill conditions in earshot, these can be pre cast, spirits tear up the monoliths, and spirit's gift can save the party if timed right with signet of spirits, and as mentioned cautery sig for paragons, fall back to move the party, lots of energy, damage and party buffing utility that abby can't strip. Also We Shall Return is a decent Anti-wipe, even on a paragon secondary.
Another hint, Everytime you kill 2 monoliths you get morale, so give everybody res signets instead of normal res skills. Free daze proof full health res that recharges constantly is win. Also pretty much any long recgarge skill that would normally be prohibitive works, for example spirits gift, even though it may get ripped recharges fast, By Ural's Hammer! Will be charged constantly. Ray of Judgement or other nukes like savanah heat, fire storm and whatnot can be used by heroes every time a set of monoliths dies, it gets recharged, use glyph of lesser and hit the next mob or abby.
Just watch out for the word of madness. Abbadon with ALWAYS cast it about 2 seconds after he puts his head down, and seemingly randomly throughout the fight. If you time it JUST right, you can get pain inverter on him the second before he does word (when he pouts his head down)for massive damage. Pain inverter will only last about 1 second on abbadon, so make it count, but if you do, and you have spirits in play he will lose almost or over 1000 health. It's also decent for the dervish monoliths and claws.
Sometimes you just get a punk run, a set of monoliths will glitch and you'll be fighting a live monolith while trying to attack abbadon or they'll bind the wrong chain, you'll get just really lame claw spawns(i've had like 3 at once in the backline...) the monos will just refuse to die, but I've managed to turn abby's gate into a farmy experience. I can beat it in 5-10 minutes and I get stupid rich on Z-Coins when it comes around.
