Interesting, I’m the opposite. Being a Sagat player from Street Fighter IV, I’m doing better in this game (3300 LP) than I would have imagined. I’ve been dominating players who I couldn’t touch in IV. One guy used to be over 4000 pp, now he can’t even get past ultra bronze. I suppose it depends on who you played in IV, some skills translate over, some don’t. For example, my friend has great execution and was amazing with Ibuki and her canned setups, but seems to have lacked fundamentals. I on the other hand have poor execution, but stronger fundamentals, which seems to suit me better in this game. Also poor execution doesn’t seem to handicap me in this game like it did IV.
Edit: On further reflection, I suspect It could also be that it is early on. Once the meta evolves, I expect to drop rank and not be able to compete with Gold players like I currently can. Same thing happened in Starcraft 2, I did well early (High diamond), but as the meta evolved it became harder and harder for me to compete.
