Honestly easy +1. And no, it's not cause he's my friend. Let me break it down for y'all.
As a DL I'm tasked with picking staff members for my division. When I do this I look for a few key things. That's maturity (as in knowing when to be serious and when to have a laugh), work ethic (how well you do your job and making sure you don't cut corners, etc.), and quick thinking (can you interpret a situation and make a good call on how to deal with it).
Now, Polar shows a great deal of all of these. His work ethic is rare. For example, at his IRL job I know even when it's rough, he never complains about it. He just says he'll figure it out and grinds it till he gets it right again. Maturity, he likes to troll and joke around but if his work ethic says anything it's that on our servers as staff, he's going to take it seriously and do what's right. Lastly, his quick decision making. When somethings up, he makes smart decisions that genuinely take all parties into account, and when it's something personal, he removed himself and his feelings from the situation on server.
He owns up to his mistakes and always is trying to grow/learn from them. He works hard and knows the rules. He's also incredibly active in the community accross all social circles.
So yeah, +1.
