I have zero issues with someone saying "I don't like this and I'm not spending any money further."
Someone saying "this will ruin the game" I see as childish, but their own opinion and nothing against it.
To say that "There is no way to get wood in game (besides the store)" is a flatly wrong statement.
Now if the only way was to get a lucky wood from the store out of a chest was the only way, I'd be much more inclined to agree with said posters that are claiming there is no way to get wood in game.
There are those that say that "there is no way to get wood in game at lvl to TR again at 20", I don't know how much heroic sagas grant, but the amount of work required for just the wood out of epic? I'm inclined to agree with those posters under that condition.
