Technology and cargo are now completely separate inventories, so any technology you had installed in your general inventory needs to be reinstalled in your technology inventory.
As a way of compensating for this nerf, they also added supercharged slots, which provide a buff to the technology installed in that slot. These are randomly laid out. Higher class equipment has more supercharged slots, but you may need to add slots to uncover all of the supercharged slots.
Thank you! I have to do 3 EW EX fights myself — and even though I’ve unsynced most of the older extremes, I’d still like to go back and at least sync clear all of ARR and the Monster Hunter crossover since they’re likely to come up in roulette.
Frontlines is fun but a mess. It’s chaotic and how well you do comes down to whether or not there’s a shot caller to keep everyone on track. As an individual player, your best bet is to play defensively and stay with the group at all times. It pays really well though — there’s daily bonuses for both job and series XP, and you can level jobs by queueing in on them and then switching to whatever job you prefer for PVP at the start. There are Garo achievements linked to Frontline wins if you want those glams/mounts, too.
That sounds really frustrating!
I will say that at endgame, the Hector lecture videos are considered the gold standard for guide videos and tend to be the most commonly used PF strats, and those videos do actually explain the mechanics in detail, with diagrams of how the attacks go out. So while I hope your relationship with your static improves, or you find a better one, once you reach endgame, you should hopefully have a better chance at learning the mechanics either way.
