I think they should just do whole transfer/merger of all the light servers, to achieve mid-standard servers. This would be the most seamless way of doing it. No rerolling, no reforming the guild, no re-doing anything. Every thing would stay pretty much the same, except you would see new people to play with or against.
Then they need to get serious about player driven contents (aka sandbox).
To answer OP, I just cancelled my sub, I will stick around until it runs out, so if they do it before mid-July I will still be there and see 1st hand if it is worth paying again. If they do that after mid-July, then I'll check on Vent if my guildmate are coming back, but I will be playing something else. I don't know what, but it won't be Tera (even if we have a guild extension there, which I don't think is very much active since beta anyway, TSW has potentials but issues so I didn't dig the beta, not a D fan, and while Rift is very well executed and I know a bunch of people playing it, it is not innovative.. So I am likely to play some of the games I bought over the past couple years and haven't played...
