Not unexpected but not a very wise choice. It feels like a forced promotion to me especially knowing RoNi's general attitude.
Don't get me wrong, he can be a very nice guy but he's not the type to sugarcoat his opinions, he posts what is on his mind at a time without thinking it too much through. It causes several issues and often he can't back off from his opinion after because it's simply too late.
Besides that, he's the type that when angry can really overreact things very badly and that even publicly, he's not the type of person you really want to talk to when he's mad and you can't expect his next course of action when he is. You have to wait for him to calm down but it's very hard to deal with him at the time and so he can cause things that will get people immensely pissed off.
That brings us to his leadership or management abilities, from what I've heard, Surf GG was left in a poor state and he basically told that it was up to Pim to fix it (from hearsay, if RoNi denies that, then I guess it's a he/she says kinda thing), I mean can you really respect and follow someone that leaves stuff up to you on a whim and may refuse to help you out, will you listen to someone that tends to overreact small stuff and acts in general very control hungry?
I haven't seen him really excel in solving issues either or well I've seen him create more issues than solve to be completely honest due to the aforementionned reasons. His english also may be a cause as he doesn't express himself well at times or it just doesn't come across as he intended due to the language barrier.
Additionally, I don't see the level headedness in RoNi that I see in other people. I see a hot headed person that gets mad too often and acts too much based on his feelings. I feel that when things don't go his way, he often rages and act in a way that is barely staff material, let alone CL material.
Yeah he works hard from time to time, yeah he's been here for years. But being an oldie and working hard does not mean you deserve or are ready for a promotion. Promoting someone to let him show he's capable isn't a very viable strategy either. People have to be capable before you promote them to eliminate any risk of issues coming up.
