Class combinations and tactics

So ive given this a few thoughts of how some classes can lead skills into eachother. This is more ideas for specific situations and possible counters. 1) Aggressive knockback- Used more on charging, striker titan can use fist of havok or shoulder bash into the starting npcs, bladedancer hunter can follow with blink strike or arc blade, voidwalker warlock can add suppressive fire using nova bomb 2) Aggressive defense- This will be a great setup for raids, use a defender titan to deploy ward of dawn in the enemy line of fire (built to drop orbs of light when attacked), let orbs of light pool from this. Unleash all specials from other team mates and once down gather near the team firesinger to use radiance and lower all cooldowns. With lower cooldowns striker titans and bladedancer hunters can wave clear using their skills. 3) Corridor running- Tight long stretches packed with npcs, best skills will be fist of havok on large groups to push back, the lingering electrical damage skill will push them back, warlock voidwalkers and sunsingers can rain down massive AOE damage (larger spread groups are best for warlocks, tightly packed groups are best for titans).
