Personally I think the topic has been done to death.... but it's good to keep it going so more players are made aware of it. Any add-on that promotes sound PvP strategy is ok in my book (and I'm a healer, on 5 different toons).
Some people go with a technical argument... that by marking enemies it circumnavigates blizzards block on raid markers on enemies. My answer to that is it's not a raid marker, it's an individual marking... it's not technically a mark, but rather a graphic modification to the enemy's status bar. It may be decided that this is illegal for whatever reason, but that's for blizzard to decide. I have yet to see an argument how it (outside the context of the net effect) is inherently bad. *Edit: Oh, and it's not visable when the healer is in stealth, so please stop with that hacking argument or comparing it to hunters mark.
There's many arguments from healers about how difficult it is to survive in 8v1 situations... honestly any team that sends 8 players to a given base or on a given objective is usually playing poorly... for example in AB they can send 8 players to the LM... that's half of their team at one base and there's no reason your team can't make gains elsewhere if this is the case. I would say a 5v3 situation is common in most decently played bgs, and a healer on the 3 side can do well... it becomes much more difficult with 5 focusing on the healer, but still a winable battle for the decently geared healer, as the healer has cooldowns and abilities to stay alive, provided his/her two other teammates are protecting him/her.
Some people just play the "bad card", as in arguing that it's something that helps bads play well... well, maybe, but that's the objective of any add-on... to make tedious tasks easier and more accessable. There's still going to be bads that will break CC on enemy healers, because they have a red marking above them, which will be beneficial to healers, so that "bad" argument carries no weight with me. Also, said "bads" still have to kill the healer, and given as bad as some of the bads are, I don't see that happening all the time. It just helps with assisting situational awareness, that's all... it doesn't play the game for anyone.
As noted in the previous thread, the add-on also marks healers on your own team, which is good for healers, as it helps the dps recognize the healers on their own team so they can offer peels, as well as avoid leaving healers alone to defend a base, or to lead the charge on a base.
And in the end... no matter what role I play, battlegrounds are always more fun when they're challenging... fun when my team plays well and the enemy plays well. This add-on in my opinion makes battlegrounds much more fun, because both teams in all likelyhoold will be using more sound strategy making the battles more fun and challenging.
Keep bumping the thread with your love and hate, because I look forward to getting more and more players on board with this add-on.
