Titan skating is easy imo. Aa for snipers, I get annoyed with campers as well. It's a boring play style and especially when you have a high aim assist sniper with Hidden Hand, it can be a very easy tactic. However, now that flinch has been increased on snipers and snipers have to deal with more shotgun warriors, I would say it takes a lot more skill than you give ut credit. Especially, if the sniper has low aim assist. Fusion rifles take the most skill though imo.
