Due to shield recharge mechanics, it may be noticed that Ward will not affect recharge delay as expected. Any given delay will not be reduced to `D = d * (1+b)`, but will actually follow the formula `D = d/(1-b)`, where D is the final recharge delay, d is the recharge delay on the item card, and b is the sum of all recharge delay bonuses combined additively. This means that if Ward is at level 11, it will not reduce a shield of delay 2.00s to `2.00s * (1+(-0.88) = 0.24s`, but will reduce a delay of 2.00s to `2.00s / (1 - (-0.88)) = 1.06s`
There is no hard cap on shield recharge delay. However, greater reductions of recharge delay will see diminishing returns.
With a minimum recharge delay Cracked Sash (0.98s) and Ward at level 11, and three Tactician Axton teammates, delay can potentially be as quick as 0.32 seconds, resulting in an extremely resilient Maya.
