I have started a game with the lanun and can give you a feedback on them.
I never played them before so i loaded a few times to figure out the best research path in the early stage, playing on king epic, agressive ai, agressive barbs, no tech trade, basicly the standard setting im playing on.
The start was easier than expected, direct research of fishing pushed the capital and from the start i didnt have to go down with the research unless i wanted to save some money, so the economy is the best from the start certainly. The isle has been tweaked already as i know, and the place is not too bad but again i have to ask for more hills, the northern part has only 1 hill covered with jungle and the southern has only 1 hill with 3 hammers. I know they shall have to struggle but i think its a bit too handicapped. Also you could add 2-3 goodie huts on the startisle, they should get the same chance of getting a free tech or at least some cash like others, as playing ljosfalar i always get at least 2 free techs and thats a huge advantage. Why 2 graveyards and a temple ? I thought about leaving one to train the units, but the place is too narrow.
Also this time most of the AIs are developing differently, by turn 170 the luchiurp are extinguished by orc, barbarian raids and even the ljosfalar attacked them

The calabim lost their capital due to an early attack of orthus, funnily the griogi managed to capture it so they are a bit better this time while the calabim are about to die out next. The Khazad lost already a settlement to the doviello, they wont get so strong this time i think. Hippus Ljosfalar and the Clan are doing great, they benefit from the missing dwarfes and of course im not around to punish them

The blaspheraphs are again in the lead, also the kuriotates are doing good, as they do not suffer from barbarian attacks probably. The malakim are really bad though, even you said they are the best they suck again. Reasons are strong barbarian activity and the lack of hammers certainly.
