Why? Right now Searing Totem seems dull and it doesn't add to/coincide with how Searing Totem works in WoW. When I have one come up in Hearthstone, it's disappointing. It feels like I just wasted 2 mana. In my opinion, the other three totems, while they might not always be useful, have some kind of benefit depending on your play style.
While some may argue that the other classes also get 1/1 for 2 as their hero power, my intent is to suggest some comparable options which will feel more inline with a Shaman.
First, change Searing Totem to a 0/1 for 2, making it very easy to kill. Second have it deal 1 damage at the end of each turn... but to whom/what? This is where the discussion comes in.
A) Deal 1 damage to a random enemy minion OR hero.
B) Deal 1 damage to X random enemy minions (2? 3 might be a bit much).
C) Deal 1 damage to target enemy minion or hero.
D) Deal 1 damage to minions across from Searing Totem.
My opinion is that A would be the most balanced.
Dealing damage to multiple minions (B) might be overkill but I'm still very much learning the game.
Option C would seem reasonable given how cost/damage relationship works, but doesn't feel very "Shamany"
D is the most interesting IMO... Blizzard has implemented some location based mechanics (Like Flametongue Totem) which might make D plausible. It would also add a neat element to a match as far as card location on the board and force players to keep an even or odd number of cards on the table to manage damage until Searing Totem is dealt with. For example, shaman has 5 cards, the opponent has 5, meaning only 1 is directly across from the totem, so it is the only one damaged, however, if the opponent had 6 cards, 2 of them would be across from the totem, causing damage to both cards.. Which, at 0/1, should be easy. However, if the Shaman has 5 cards, and the opponent has 1 or 2, odds are none will be across from the totem, meaning it deals no damage. This card count/positioning allows both sides to control Searing Totems damage and also functions much like it does in WoW.
Hopefully this is new, and I didn't just reiterate someones idea from another post. I just got into the beta, so there is still a lot of reading and learning to do!
