The easiest way to avoid the Thargoids is not to logon at all.
For me it's not really about "avoiding Thargoids". I've engaged in AX combat before and over the last 2 years I had supported Salvation precisely to spice things up again. I still have dedicated AX ships in my fleet that have seen plenty of AX Combat. But for my personal taste, combat in Elite is either too boring (endlessly chipping away at HP sponges in human CZs) or overly complicated (learning cold orbiting techniques, grinding material to synth ammo and heatsinks during combat in AX). Also it's a shame that AX has no "chill" AXCZs (like a "scouts only" CZ). Even in low CZs interceptors will appear eventually and you have to deal with them in an appropriately fitted ship.
We will see what Update 14 brings to the table, but I am not really expecting anything that will get me "hyped" enough to play Elite for more than a few days (at best) again.
