Noddy,
There will come a time (currently estimated to be at least 18 months in the future) when a newcomer to the game will be too late to gain the merits or credits from clearing monsters off Thord-Artin. Presumably, it will also be too late at that point to gain any construction points from rebuilding the island, and possibly even too late to gain monstology ranks by repopulating the island with Larkinor monsters. This is inevitable with all events. I'm sure many of the current diggers would have loved to have been in on the diamond shovel construction event, but you win some and you lose some.
From my understanding (and someone please correct me if I'm wrong), until the last square of Thord-Artin invaders has been cleared, you will still be able to reap of all the benefits of the island as a late arrival. There is no (known) bonus to being the first character to step foot on the first cleared space of the island. In fact, once the first space is cleared, we will merely continue clearing squares until we have cleared enough to start building. I have no idea how many this will be, but from sailing around the outside, Thord-Artin appears to have 83 spaces. I presume buildings will exist on about half of the spaces, similar to the island of Larkinor.
> Does all the extra exp. points, extra attributes,
No one is getting any extra attributes. It's debatable if anyone is getting any extra experience points. My records show it's a very thin margin for my character (depending on how many times I die and have to boat myself all the way back). Although others have different opinions. The truth of the matter is, once they took the Larkinor monsters off this island, the conquest rate dropped by about 75%. This tells me it's not all that wonderful over here.
Also, I can't help but noticing that my character is ranked #125 of the experience level toplist, but is #4 on the conquest toplist. In other words, it appears as though a lot of upper level characters aren't bothering to spend much time on Thord-Artin just yet.
The good news for you, and anyone else already in the game, is there is PLENTY of time left to get to the island and start helping out. It only takes a smart subscriber about 6 weeks worth of clicks (plus the bonus 12000) to get a character to level 30. If you're less conservative with your clicks, you should still get to 30 in close to 10 weeks.
I guess I had a lot to say...
