Think for a moment that someone might post a realistic and fair-minded perspective on PvP balance, rather than one of simple self-promotion of their class or their team's lineup. Sound farfetched? Then consider that you yourself may be guilty of self-promoting, and you are just assuming that everyone else is doing the same as you.
But Blizzard doesn't read these forums. They barely even read their own. Self-promoting here is obviously pointless. No one you could possibly convince here has any power to change your or your team's status.
Additionally, what do you do about a player who has 5 classes and 15 teams that he plays competitively? Which one is he promoting when he posts? I have exactly that, and my interest in any debate is as a strategy buff and lover of competitive and balanced PvP. The reason I am posting that your class is overpowered is because in my - modesty aside - rather expert opinion, it is. I would much prefer that you argue this strategic point on a level of strategy, rather than a level of self-interest, such as "you don't have a druid on this team" and the like.
What makes a druid the worst 5v5 healer in your opinion? Lack of single-target throughput? Inability to dispel magic effects? Vulnerablilty of hot spells to purge? How are these perceived weaknesses enough to cancel out their strengths of mobility, crowd control, and instant cast heals? It is not enough to say they are under-represented, because power is only one of many factors affecting representation.
First of all, i'm sure molp and i, the people that continue to reply in this thread are fully aware that no one from blizzard reads these forums. So i can just as easily turn it around and say since we have nothing to gain, we are speaking from the heart.
I also play multiple classes, i have arena'd on a spriest, druid, rogue, hunter, warrior, warlock, and mage. In addition to trying the remaining classes on the ptr at least.
I have more experience with rogues, mages and druids.
Druids are so strong in 2s because they can heal through 1 or 2 people's damage with hots while staying mobile and being able to los everything.
This is exactly why druids are weak in 5v5--->hot healing. Which is not enough to heal through mortal strike and 2 other dps by themselves like say, a paladin can. And it is not possible to kite/los 3 or 4 dps classes.
Druids main healing on gib teams are different, they rely on killing someone on the other team extremely quickly or forcing the opposing focus to play so defensively that they might as well not be there. This is very hit or miss though, and is usually why you see many 4 dps teams in the top 20-30 but not in the top 5.
No magic dispel, very limited support/buffs for other classes. If a druid is running with 2 healers, the other one will get sheeped/feared leaving the druid with just hots to heal through everything. Motw is the worst buff given by any class. The only in combat/support buffs the druid gives are decurse and abolish poison. Mages can handle decurse just as well.
-Shamans bring offensive dispels, bloodlust, anti-cc totems, and windfury for warriors.
-Paladins bring their blessings which include melee immunity, snare immunity, the best scaling buff in the game and the best mana regen buff in the game. Only one can be active on each person but their upside is unmatched.
-Priests bring mass dispel, mana burn, offensive and defensive dispels and fort+shadow protection.
-Druids bring motw, cyclone, and hots, which are their heals. And for how good cyclone is, it is what most non-gib 5v5 druids are doing. Cycling cyclones and throwing hots every so often. People in this thread are complaining about the one thing that makes druids barely viable in 5s.
Lastly, relative power is a big deal when talking about representation in the top teams. To say, "Well druids are the lowest pop class so they should be the lowest represented in the top 20 of every bg," Is not very valid because any of those top teams will have access to the best of the best druids. Look at Sereianna or whatever his name is, he does 2s and 3s with quite possibly the best druid in the world, yet he doesnt use him in 5s. This speaks for itself.
