I'd give it a go, doesn't hurt to try while it is still in free-mode. However, population is ant-size (empire-side) from what I've seen so far.
Not sure about League's side. Anyway, told somebody about it from f2p and we've been here on p2p since, leveling. It's okay and all, but seems like the extra players I ran into around aren't so extra but alts of the already existing players I seen when I first started. They also seem to be about their business, which makes it to feel like you're in Tomb Raider mode, even if they're around.
This is from my point-of-view on empire side mind you. Pity too, because I am not really feelin' the f2p anymore; grinding extensively and making a video game a part-time/full-time job is not for me nor will it ever be. So, I am giving this server a shot.
Lastly, They should revamp the price on this server when it goes off free-mode. Cheap-Cheap! Something like 5 bucks, plus monthly rewards for those who pay to play 'til the server kicks back with players (if possible), then they can re-adjust the pricing but within reason. Because, I'd love to play on this server instead.
Just my 2 pennies!
