Reading some of the posts on Uhall, perhaps simply increasing the bank box storage from 125 to around 500 might have a big impact.
I'm thinking the issue is that and skill gain, from what I'm reading, but yeah... That seems to be a major issue for most. Its damn hard to live out of a bankbox with 125 items or less. In todays game, that number is completely unreasonable. In fact, I'd rather see it increased to 1000 items if its doable.
I can tell you first hand, that once you're addicted to Siege and have been here 6 months to a year, the houses and crap you have on other shards becomes less and less important. A year into Siege I dropped houses and stored items in multiple banks, on multiple characters and multiple pack beetles on a couple accounts. Gave the rest away and never played there again. heh
I think we need the RoT timers tweaked down a bit, but I'd also really like to see some periodic, limited time only events for raising skill. A few months of blackrock gain areas, then next year maybe a few months of powerhour, in addition to daily RoT... or something to that effect. If the Devs would do that for us and we could announce it once or twice a year, I think this shard would bounce back nicely.
