Something interesting that megas know about claim towers that a lot of folks might not:
Each company, even a company of one, begins with 200 claim points. So, what happens when that mega (at 200/200 claim points spent) steamrolls a lawless company of two and wants to claim their stuff? Easy!
Someone drops from the company, claims it, and then rejoins the company. For example, let's say that the mega company, INCELZerg, needs to drop a claim, but is capped at 200/200. Pirate MegaN00b03 drops from the company; MegaN00b03 is now the only member of MegaN00b03 Company with 0/200 claim point, so he starts claiming like crazy until his solo company is also 200/200. Now comes the fun part! INCELZerg re-invites MegaNoob03 back, and all of MegaN00b's claims become owned by his old company. INCELZerg's claim points are now effectively 400/200. Repeat, repeat, repeat... Honestly, you don't even need to be in a mega - a company of two people effectively has infinite claim points.
Basically, each company needs to be HARD CAPPED at 200 claim points. For example, If a 200/200 company merges with a 100/200, then all of the 100/200 company's claims instantly demo.
I think the intention of claimable lawless was to provide an ownership option for solos and smaller companies. But as it is now, island-owning megas are using the island claim exploit to purge lawless islands and claim every square inch.
Quick edit: Another fun hobby is to sail around claimable lawless islands looking for poor saps who have armored docks within claim tower radius. Destroy the 400k hp claim tower, place your own, demo your new armored dock for 5k gold. Continue on.
