I did not get a chance to play Thunder until after December 1st, so I have no idea what it was like to play him when he was released, but his concussion grenade is lacking in comparison to Fragger.
Even when I get flashed point blank by one of his grenades, I have no problem either getting myself to safety because the hud remains on screen to give me a point of reference or I’m able to kill him because nameplates as well as hit sounds aren’t disabled.
Well his concussion grenade was lacking compared to Fragger’s grenade before December 1, it just affected mouse sensitivity as well and could be cooked. You’d think he’d have the k-121 (or w/e Fragger’s LMG is called) to make up for his non-lethal ability as opposed to the MK46 which actually suits Fragger’s role better with him throwing a grenade and finishing off people hurt by it.
His concussion grenades on release made it so people’s mouse sensitive would tense up, along with blinding and decreasing movement speed but we can’t have a character who tosses nonlethal stunning grenades that stun effectively, noooo.
Many people complained about it so SD scrapped it.
Shoe said it’s not set in stone and I really hope that it’s true.
As @SaulWolfden said, giving Thunder and Fragger their original LMGs back to each other is a good idea as it fits their playstyle much better.
As for the lack of cooking and wider area of effect but shorter fuse time, I personally don’t mind as it makes playing both as Thunder and Fragger and against them different.
