Hi Will@MWEB,
I just quickly want to add my own bit of experience to the mix.
A few weeks back i used to have great latency with WoW + Mweb + Proxy, I use to actually get green numbers hovering around 280-290. Recently I have not been able to achieve that with Mweb and normally now hover around 310-350. Nothing major to complain about though, but something that is just a tad bit annoying is that I've noticed a Cindarella pattern coming up with my uncapped 4mbs account... as soon as midnight rolls on the Mweb account goes down the drain.
Even with my proxy in place my latency goes through the roof. I'm then forced to log off, disconnected my internet, reconnect with my backup prepaid account and continue playing at a nice 230-280. I'm not going to complain since having the backup is only necessary after midnight or when some other disaster hits my mweb account, but I would like to add my own experience in there for you.
Could this have something to do with P2P opening up late at night? Might be, I don't know. Other than that my mweb account works and I'm sure one day this problem will be fixed.
