The person complains about the memory usage like that is a large number. Try testing City of Heros. The current patch released to the beta testers has a memory leak, it had city of heros taking up a gig and a half of memory on my system. Now that's a memory leak. 350k in memory is below average for an online mmo, in fact its about average to most games period now of days.
In the words of Karyuu, "Have a nice day, somewhere else."
