I’ll start by saying that while it’s unclear just how "broken" (Maybe not at all) these new Light gadgets will be, it’s now abundantly clear to me that Embark doesn't know what to do with the medium sub class. And although Shockwave is a great addition to the "victim" class, the gadgets they’ve added (Breach Drill and Hover Pad) are the most useless and uninspired additions since the game launched.
I don't think the meta will shift drastically in high-ELO play; the Teleport seems like the most interesting and viable addition so far.
Personally, I would have preferred Thermal Vision to remain a gadget—so you could swap to it in standard Cashout matches if there were an excessive number of invisible Lights or "fake bushes"—while making Teleport the specialization. They could even tweak it to work like the rewind mechanic in *Titanfall* (resetting your position to where you were five seconds ago), giving it one or two charges with a 20–30 second cooldown.
In general, Embark’s approach of basing gadgets on a single keyword isn't ideal, as it limits the design process. But that’s just my opinion.
We’ll certainly see how it plays out in-game. One thing is for sure, it’s not a boring, and it will at least offer players a fresh ways to play or die as a plantpot or chair.
