Is it?
I consider myself fortunate, that throughout the existence of SBMM, I had very little trouble as far as game breaking/rage inducing lag goes.
This IB started a little rough for me, but nothing unbearable. Now that the fix has gone live for this banner, it's gotten even better.
I would guess geography plays into connectivity, as does user demand in a given area. Not including weather, service, and related outages, why do many people seem to have such serious problems with lag?
I'm looking for an answer other than "everyone else is lagging, I green bar FTW". I play the same game everyone else does, and rubber banding, teleporting, delayed damage, etc are uncommon in my experience.
What's your connection like in your area?
