[spoiler]Fragger initiates teamfights by making massive bursts of damage to the team on the recieving end while Thunder allows teamfights to happen through his concussion grenades. To explain that, i’m gonna go the easy route and explain it with comparaisons:
Think of Thunder as the one lighting up a dynamite stick while Fragger is the dynamite stick itself. I’f you follow that logic, Thunder would be better for coordinated 5-men pushes while Fragger would be better when your team is outnumbered in general, because of that, it’s not uncommon to see teams rocking both a Thunder and a Fragger. It all depends on your mood and playstyle.[/spoiler]
(Short version: -You like passive, team oriented approaches? Rock a Thunder.
-You want to be more active in choke-points? Go Fragger.)
Both 2’s:
[spoiler]Besides the absolute lack of abilities that are directly beneficial to your team, they’re pretty good and all rounded mercs, the only thing you have to worry about is not trapping yourself into bad habits and decisions.
I said earlier that Thunder is more oriented towards pepole with a tendancy to passivity: and this is a problem, because of this habit, it’s pretty often that you’ll see Thunder users popping flashes at pepole, then either staying in the background or just simply not leading the charge, forgetting that they’re using the second tankiest merc in the game.
You have 160 hp, don’t be afraid to jack in first instead of your medic behind you when everyone is blind.
On the opposite side of things however, you’ll frequently see Fraggers overestimating their ability to kill everything and charge head-first into everyone despite their team not being ready to take on the other one (which you seem to be the type of guy, seeing as you think low levels are completely helpless, they still have guns you know), this leads to them either dying or them lone-wolfing around the map.
In both cases, they leave their teams just as massively crippled as if they lost their medics in higher levels of play, don’t be these guys.[/spoiler]
4(why did we jump from 2 to 4???):
[spoiler]I’f you can’t handle the K121’s recoil and spread, you’re doing something wrong.
I’d say you should practice it, just simply be aware that this gun is made for CQB-mid range encounters and that trying to aim down sights with it when engaging fights will get you killed. You could do that mid-fight i’f you’re really stuggling past a certain amount of bullets though, but i don’t really recommend this.[/spoiler]
