This is how you should go if you want to have fun with specializations:
51 - 60: Pioneer - Fast Track just gets you up so quickly. It’s hilarious how much that little 500 xp boost helps. If you want to rank up quick, do it.
61 - 70: Operator - Operator is for people who love Mechs, Tanks and Banshees, all it does is lower EMP time because the EMP time in H4 takes forever, and sometimes even the lowered EMP time doesn’t help. Sometimes.
71 - 80: Tracker - You remember those annoying times where you get the choice of Plasma grenades, Needler and speed boost? Yeah, you can turn that into Fuel Rod, Splaser and damage boost. It’s great for support players that get assists a lot and even better for main slayers that actually get kills.
81 - 90: Rogue - Tried sniping but that noob on the opposite side on that scope keep making you miss shots because his shooting you? Stability stops that flinch in it’s tracks. Get a guest in a custom game and test the difference.
91 - 100: Pathfinder - That lonely turret that chills in the middle of Ragnarok kills a Mantis in seconds if you have this on. It also applies to Gauss, rocket and default hogs I think.
101 - 110: Wetwork - Good for assassinations. Nothing more. Has one of the best helmets in the game in my opinion.
111 - 120: Engineer - This is a poor man’s Tracker. It tells where ordance drops are going to drop, chances are it’s not near you. Ok for callout about weapons.
121 - 130: Stalker - There is a reason why this is last. This is like Revenge deathstreak in CoD, tells you where the last kid that killed you. If you’re being spawnkilled, it doesn’t really help. But, when you hit the big 130, you’re stuck with the last specialization on your played card, and it’s pretty funn tbh.
Just some advice.
