serious question.. i have 4k hours in this game but never did any guardian or thargoid stuff.. just worked towards getting my carrier, all my pve ships and bubble engineering (not even done colonia yet). I feel really behind on what now seems to be the whole point of the game, i guess i didnt anticipate elite becoming an on-rails story. Is it even worth trying to get into the AX stuff now with no guardian gear or experience with AX combat? feels too late tbh.
If I can give you my opinion, I have roughly the same number of hours as you, and I tend not to rush into things.
At some point I decided to do AX stuff, because I had not tried it, yet, and found my own path, without chasing the meta (but still following advice).
When the Thargoid war began, I have occasionally joined the various activities, but once again without being in a hurry to be among the first.
What I think will happen now is that, no matter what the narrative brings, the new game mechanics introduced will stay, perhaps as secondary objectives, or in backwater systems (I might be totally wrong, but still hope I'm not), so that everyone will have time to engage with them in due time, should they be interested.
If you're not one who wants to rush, my suggestion is to start doing AX stuff at your own pace, don't burn yourself out, and enjoy the process/progress. You could be late for this phase of the story, but not for these additional mechanics, which might as well be here to stay.
