Here you can post ideas for Titan loadouts. :-)
For a start:
Name: Tesla (or Zeus as an alternative)
Primary Weapon: Arc Cannon
Shoots lightning charges. If fully charged, the lightning strike jumps to another two targets that are close to the main target. Deals extra damage to all kind of shields.
Offensive Ability: Thunderbolt
Enemy Titans hit by Thunderbolt can't use abilities for a few seconds.
Tactical Ability: Arc Mine
Deploys an Arc Mine that stuns the first Titan to step on it for a few seconds.
Defensive Ability: Lightning Surge
Tesla unleashes a Lightning Surge to enemy Titans in front of him. As long as an enemy Titan is hit by Lightning Surge, its vision is interfered and movement speed reduced.
Tesla releases a massive EMP shockwave, stunning all Titans in an area around him.
Concept-idea: The essence of the Tesla or Zeus-concept is disturbing his enemies and creating an opening for an attack or defending your allies while doing so. Use Arc Mine to lure enemy Titans into it and kill them or use it to escape. Shoot your Thunderbolt on them to make them unable to use defensive abilities and attack them or use it so they can't use their offensive abilities on you and your allies.
The downside of Tesla is that his abilities themselves don't deal a lot of damage, except for shields. This was another important part: Since Tone and Legion are so prominent in Titanfall 2, Arc Cannon is the right weapon to deal with them and quickly destroy their shields. I also thought about letting Thunderbolt deal a lot of damage to shields, but I think that ability is strong enough as it is.
