Idk about thermal because it has it's advantages and disadvantages but I totally agree with you on the Tilly. All you need as a good camping spot and bam you just got 3 kills
Good point, the thermal does have the disadvantages.
I get why it was brought in. Sniping on a heavy snow map is, difficult for some one who is not a pro at sniping the thermal is very usefull. Good that it forces a sniper to come close range. Tilly's is where is just goes down hill and is really frustrating. I don't mind getting sniped by them. Been playing for so long now with them its just part of the game. Stay close low and keep eyes open for cover. Also red smoke. Its when you see people run and gun with them. Espicially when they are on your team vs a guy who has excellent aim. If your going to snipe then snipe, but why run and gun with it. When you lose rounds because he just spams in close range is annoying and frustrating.
I'm not a huge fan of the DLC. If thermal and specializations were not added they would be better. The tilly's and thermals are just war to overpowered.
The specialization system screwed up what little weapon distribution balance there was between teams giving the terrorists the Sr25 or G36 but it also gave players more options in attachments like the foregrip on the M16 when for some unfathomable reason you couldn't before and other rifles or the regular suppressor on all SMGs...hate the very idea of unlocks but it does have ups and downs.
The thermal was just poorly balanced they probably should of just left the "white" filter so it wasn't so easy to scan and see enemies glaring out at you as well as limit the magnifications. Ideally there would be two versions of it one locked at 2x and one locked at 4x so you have to choose between the ability to scan and the ability to snipe accurately.
But in the end even without the DLC you will still play in rooms where people have it...and at this point everyone else is going to.
