Personally, I like the one we have.
2 and 3 are... Well, I don't know why you were thinking thunder, but I woulsn't vote for 2 or 3. lol
I like number 4, but when it's sized down to fit the guild icon size it's going to look horrible,.
Which is why I vote to stay.
In the battle of Good and Evil, there are only so many Legos.
