This will just be lots of ideas crammed together into 1 discussion.
Cloak and Phase Shift: Cloak can see all pilots that are cloaked within a 15 metre range and Phase Shift can do the same with pilots and Ronins.
New Modes: Hellstorm; You and 9 other pilots (10 pilots per team) will either be tasked with attacking or defending an IMC stronghold, attackers must first get though a blockade of IMC ships onboard a carrier while manning the turrets and dealing with the defending pilots boarding ,then getting into your Titan and falling in inside it instead of calling it in and laying siege to the stronghold
Titans should work on a modular system:
Hull (When destroyed the hatch will be removed from exposing the pilot, Titans can remove compatible, compatible as in Ion can take from Ion Scorch from Scorch etc, parts from destroyed Titans )
Joints (Reduces mobility when damaged or clogged with shrapnel, pilots can remove shrapnel from joints to repair joints)
Optics (Reduced sight when damaged, same as hull repair)
Weapon (Damage accuracy and ranged reduced when damaged, can swap any weapon but keeps abilities)
New Boost: Arc Traps (you all know what they do)
New Ordinance: Shock Grenade (when it explodes the shockwave throws you back dealing 50 dmg and 75 dmg if you hit a wall also makes you fall and lie down for 3 seconds)
New Guns: G209 (Automatic sniper rifle with a 10 round clip and adjustable zoom, chest and head 100 dmg)
F9 SLR (self loading rifle, assault rifle): The G2’s big brother has an 18 round clip and deals 100 head and body damage
Prime Titans should have a slight health and damage buff and not just be aesthetic.
Create your own pilot and camos
Advanced Titan melee combat (wrestling, disarming etc)
