Removing safe zones/timers with no allotment for loading times/crashes isn't the best idea.
Couple ideas.
1) Put "carebear" buff not only on bots that port through, but any bot within 1000m of a terminal on a beta outpost when someone ports through. Prevents all combat with other bears for x seconds.
2) There's nothing that says one input can't have many outputs. Include "randomizer" element in transport terminals to beta islands that places people who port to a beta in one of six or so landing spots of x-distance apart. Very low safe timer (only to allow for computer load). Obviously, if a corp wants to go through as a unit, allow squad leaders to check a "port as unit" option that would funnel all squaddies to one location.
3) Stronger corp leaders. Why in the f*** is there so much Epriton on the market, and for under 10 Nic??? Why are corp leaders not outright banning the sale to the market? Trade it between established corps that can maintain an island presence, don't sell it to scrubs like me. You give me no reason to ever join a corp and go get some because of your greed and weak leadership - I can buy everything I find too dangerous to get myself and still make a killing. (And speaking of, why isn't seller listed on market?)
The second part of that is the devs need to make it a much higher priority to incorporate more harvestables on beta islands only, and more minerals as well, and change existing high level recipes without notice to include the new mats.
Finally, should give the Devs some patience on this. It's pretty difficult to find an amicable solution that most sides can even tolerate, much less enjoy.
Festive yuletidey greetings.
