I am a lost player of DAoC that doesn't realise how can he have been nearly 2 years without playing DAoC

I've been reading somethings, I left DAoC when I was in SI before Foundations, and I would appreciate some updates on how things work
Mainly I have some questions:
- How does the cluster work? are we together with Excalibur only for the frontiers? PvE raids how do they work nowadays
- is PvE as boring as i used to be or has it gottten better with expansions?
- Is it easy to go in random RvR or now everyobdy is pro in guilds?
- Is the free trial only valid in the US?
Any other info you give me is really really appreciated. Thanks for responding!!!!
Cheers,
