Lets go 5 steps back and frame what we are talking about here. There are 3 things in this game that group cleanse, Cleansing Power tactic, Efficient Patching tactic, and Khaine's Withdrawal morale 2 for Dok. The original post seems to be written from the perspective of a WP and not a Dok. The focus seems to be on the tactic and does not include the Dok morale.
Some tactic's in this game have a inter-relationship with the opposing faction morale's. One example on how there are tactic's having a inter-relationship with the opposing faction's morale is Transfer magic tactic from the AM and You weren't using Dat m3 from the shaman. Both are AE ap drains but conducted differently. The tactic version has a less effect but can be used constantly and the morale version has a more dramatic affect but is tied to a 1 minute cooldown. The morale version also are usually tied to a class that could morale pump to gain faster access then normal. There are tons more examples with specific tactic's and specific morale's having a inter-relationship. Meaning, they are tied to each other as far as faction to faction balance is concerned. I am skipping more tactic/morale relationships in a effort to keep this short.
Cleansing Power tactic and Khaine's Withdrawal morale have this tactic to morale relationship. Some of the original balance was set up like this. Mythic screwed up a lot of the balance in the beginning of this game. They also screwed up a lot of the changes. I think mythic made a mistake of giving the Dok a tactic to cleanse because they already had a Khaine's Withdrawal morale 2.
Sidenote: If you know your history Dok's had a single target morale pump in this game at one time. The Dok could have rapidly pumped up his morale to gain earlier then normal access to their morale 2, Khaine's Withdrawal, in the fight.
Efficient patching tactic did not exist originally. It replaced a tactic called persistent rending.
Group cleanse quick description of the ingame at the moment differencse and similarities
Is Efficient patching tactic up for discussion to be removed in this thread? I think this tactic creates imbalances and was a lazy fix by mythic. I could go into more detail but trying to keep it short.
If Efficient patching tactic is to stay, should it be directly mirrored with the Cleansing power tactic? Or should Efficient patching tactic be worse because Dok's have access to Khaine's Withdrawal morale 2?
Is Khaine's Withdrawal changes up for discussion in this thread? It is a Group Cleanse and it is the best group cleanse in this game. It is tied to morale with a 1 minute cooldown, so it should be the best group cleanse. I think it would be a mistake if we ignored what Dok's have access too, and should be part of the discussion. Since Khaine's Withdrawal is morale this brings in morale's into the discussion and potentially morale gain rates.
Should the faction to faction balance of the group cleanse effect available in this game be discussed before changes are made specifically to the group cleanse tactics? I think so. I think we should try to handle the situation all in one swoop as opposed to trying to isolate and tweak. I think it would be better to look at the overall situation available to group cleanse effect then just focusing on tactic's. I think the questions I raised above should be discussed along with changes made to group cleanse effect.
I personally favor rollback's with tweaking so they don't cause the issue's on which they were discarded. Specific rollbacks will sync up with other elements this game provides which may currently seem broken but weren't at one time.
