Opportunism, meh. More like selective entering in order to stack freqs. Also, quite often, players doing this from spec will accidentally join the team they don't want to be on, spec, and retry later. That's hopping in my book. Yes I agree, if those people were to do that, it is hopping. However, I wasnt on the other team until someone used their powers to force me on that team. Without warning might I add. If you are going to moderate hopping, then make it more consistent and unbiased. Even if you were to use IP locking, you could use fail safes to prevent some abuse. Such as if you are re-entering, you cannot enter the team you were on if there is a +2 difference unless you are coming back within 45 secs (for people who lagged out). An IP lock would also benefit people who are lagging out, since they can go back on their team, if it was just a spike. The time frame could be about 15 minutes before the IP lock resets.
