Hear me out a second. You know how bastion can switch between sentry and recon mode? Let’s apply that to Echo, but take it a step further and give her 3 modes.
Just looking at her, her design is elegant and beautiful and screams support, so that would be her “base” mode, the mode she starts in at spawn.
Each mode would see her adopt 2 to 3 different abilities depending on which mode she’s in and the color of her face would change so anyone can see what mode she’s in just from looking at her.
Her abilities would be assigned to Ctrl, Alt, Shift, E, and Right Click
Primary Fire - more or less the same across all modes - Echo fires energy projectiles from the palm of her right (or left) hand, like Iron Man. Most effective against mid range enemies.
Alt - Damage mode - If in any mode other than Damage, pressing Alt will see Echo go into Damage mode. If already in Damage mode, pressing Alt will see Echo drop the mode and revert back to her default Support mode.
Ctrl - Tank mode - If in any mode other than Tank, pressing Ctrl will see Echo go into Tank mode. If already in Tank mode, pressing Ctrl will see Echo drop the mode and revert back to her default Support mode.
There should be a cooldown on how often she can switch modes, maybe 10 seconds between mode shifts.
The Shift, E, Right Click, and even the Q abilities will change depending on what mode she’s in. A few example suggestions.
Support Mode - Echo will have 100 health and 100 shields - Blue Face
Shift - Regenerate Protocol - Heals the targeted ally (like zen orb targeting) for 75. Short cooldown.
E - Protection Protocol - applies 250 shields to all allies within range and line of sight (Echo does not receive the shields). The 250 is divided equally among all allies. If the entire group is together, that’s 50 shields to each ally. If only one is nearby, that one gets 250. The shields last as long as Echo’s allies remain in range and line of sight of her. Pressing E when allies already have shielding refreshes and redistributes the shielding.
Right Click - Speed Protocol - increases Echo’s speed briefly so that she can move to allies or escape enemies more quickly
Q - Haste Protocol - Grants all allies within range and line of sight 25% increased movement and attack speed for 8 seconds.
Damage Mode - Echo will have 150 health and 50 shields - Red Face - Her primary fire and melee attacks deal 50% more damage over the Support and Tank modes
Shift - Assassination Protocol - A single, long range, high energy beam blasts forth from Echo’s forehead and strikes the selected target (target mechanic like zen orbs). High damage, long cooldown.
E - Rapid Fire Protocol - Echo’s primary fire has a greatly increased fire rate with minimal spread increase. (for faster firing when accuracy is important, such as a medium to long range target)
Right Click - Burst Fire Protocol - similar to Rapid Fire Protocol but does not reduce weapon spread and has a shorter cooldown. (for faster firing when accuracy is not as important, such as close range or large targets)
Q - Annihilation Protocol - Launches a large ball of concentrated energy that loses containment and detonates on impact, dealing high damage in a medium area.
Tank Mode - Echo will have 150 health, 50 armor, and 400 shields - Purple Face
Shift - Intervention Protocol - This is a sustained ability. Once activated it remains active until disabled. Redirects 50% of ranged attacks within a certain radius around Echo to Echo herself. Effect ends when Echo’s shields drop to zero or she presses Shift again.
E - Mitigation Protocol - All damage Echo sustains is reduced by 50% for the duration of the ability.
Right Click - Shield Recovery Protocol - Echo will regenerate her lost shields very quickly even while under attack.
Q - Bulwark Protocol - Echo creates a sustained barrier wall directly in front of her. 4 times as large as Reinhardt’s barrier with 5000 hp. Echo cannot move while Bulwark Protocol is in effect however she can use any of her other abilities at the while Bulwark Protocol is active if she so chooses. Bulwark Protocol lasts until the barrier is destroyed or she presses Q again to end it.
