For me really im good with all classes. Made it to the rank 13 on tdm leaderboards.
Titan class is a challenge for most due to the slow movement and large stages are usually a death sentence.
Each class has a purpose for me.
Scientist: Is when I am finally on a team that works together and i use Expert Flanking support.
Titan: My favorite when theres people talking trash on unskilled players. This is my Ultimate Trolling class. I use my goop cannon and whirlwind the crap out of those not paying attention especially in small stages huddled up in a corridor all aiming down the hall and i come up behind hit them with corrosive rust cannon and whirlwind them all.
Infiltrator: when everyone wants to choose Titans and Destroyers. I usually just takem down with a few shots with path blaster/Magma Dampner then finish them off with Scatter Blaster/Fireblast. Yeah Fireblast sucks as a perk but it is so fun to use when players run away on fire and die within a few seconds that it lasts. Other times ill hit them with a fireblast scatter shot then quickly use the SSR and unload before the fire wears off which kills them rather quickly.
Destroyer: Is for when I want people to fear me. I rush Anyone I see with my "Supertron" All gold color for autobot and Black/purple Decepticon. Rocket launcher/Quick lockon and Riot cannon/ion cartridge with Hover/Bugout. I rush in popem once with the rocket and finishem with some melee or a few choice riot cannon rounds. Two well placed rockets kill any class so makem count.
A good tactic to get ur opponent angry is to use the goop cannon close range and either whirlwind or energon them to death. Cancel the whirlwind as soon as you make the kill or get out of range so it can charge up faster to use again.
Scientist class is irritating to fight against nowadays due to the spamming of the homing gear shredder. Best advice is to duck behind cover the second you hear one coming and rush them as soon as that third shot misses and make the kill before they can reload. PBR can ruin someones day in a stage where everyone wants to play with Titans and Destroyers.
My best strategy is Flank...Flank....Flank....and when i think they are good and mad....Flank again.
I love shooting from around the corner and then turn into jet form, zoom around the other side and stand behin the opponent for a few seconds before unloading the sentry gun with slow perk and my NAR with Ion cartridge.
Also Infiltrators may be small and weak, but like ankle biting pomeranians the are fast and vicious. Use that against them especially with path blaster and stay away from lights out...it is garbage. Dampner and sonic blast are much better.
Last but not least.....NEVER EVER attack a Destroyer in jet form....Ive seen too many idiots come at me trying to snipe in jet form when im armed with a rocket launcher with quick lock perk. One guy flew straight at me and the second I locked on him he panicked and did the fastest nosedive into the acid death pit (Abandoned)
Whats the matter Pathetic Autobot? You look like a Decepticon peed in your cereal.
