I started a week ago and have a ~40% win rate (just for data purposes; not saying this is good) in 30/40s including like 5x 50 losses when I just started and realized I shouldn't be doing 50. Average queue time for ranged DPS in primetime is 4-8 minutes; not even worth doing outside of primetime as the queue can be 45 mins+. Twinked 40 gear certainly gives a bit of an advantage, but it's not nearly as bad as doing a 50 against i90 PVP geared players.
Just keep grinding 30/40 solo; it's not that bad. Losing 50 90% of the time would just drive me crazy; I've actually had some decent battles in the 40 (30 typically has some people who wandered over straight from Haukke Manor to try PVP and are a disaster). The queues suck, but if you have a melee DPS, just go on that; queues are super short.
