Bad in what way? The buggy/choppy-ness of the Arma2 engine or simply in a 'works in theory, doesn't in practice' way? I'd agree about the bugs but have hope they'll be wormed out in the standalone client.
Only problem i'm having with the game currently is the amount of duping going on, if you die it takes a 15 minute run to certain locations and maybe 2 or 3 server hops and you can easily get fully geared out by raiding dupers camps. I actually started playing on Sanctuary/Non-hive servers the other night just so I could go into Cherno without there being a dozen snipers all with the same loadout (AS50 w/ nato, ghillie and NVG) just sitting on the hills because theres almost no penality for dying in the context of gear. I'd guess for every legitimately spawned m107/AS50 there is atleast 200 duped ones.
