lag, R0, disconnect during leves

Before the merge I did not have this many problems while doing leves and now, everytime I try to do a leve either its battle or gathering I get lag, dc, R0 all the time. My internet latency is always with a good signal, so I ask for the moderators to avoid to talk about thats my internet, because its not! The issue comes from the leve system, why? Because if I'm not doing leves I'm ok, no lag, no R0 and no disconnecting. So I ask to fix that issue! And also the issue about the game crashing because of the 2GB of memory ram usage without been able to dump it, it wasn't fixed still!

My pc specifications are these:

Processor: AMD Sempron 2200 dual core
Memory ram : 8GB
Graphics card: Nvidia Geforce GTX 550 Ti
Internet: broadband cable connection/100Mb

2.0 isnt that far away now, hopefully its fixed then.
BTW i dont have the leve=R0 problem so maybe it is on your end?

I get that alot, and it is not from my side (sadly for SE), I have been checking my connection even during the game and the issue seems that I stop receiving signal from them, problably to compensate the surgence of other players that come near me with a leve going on and they pass through me with their leve also on and in that point the moment I see them and I start to see their leve mobs it's R0 time, resulting in near death (Rarely) or death (most of the times).
But further on, the issue seems that the game isn't still stable to allow "possibly" a large group of players solo or in a party doing or spawning leves at the same time. The moment I set foot in one of those places game crashes or I get dc, in all those cases its a median of both (50/50).
