Zilean kit synergy idea, should help solo lane Zilean.

You see how Orianna's W is a haste/slow with damage? And her E is a shield with damage as well? The abilities transition more strongly towards their supportive attributes lategame. Zilean's kit should provide similar strength to empower his solo laning capability.

The idea:

Zilean can now cast E [ Time warp ] on bombs laid on the ground : The bomb is rooted, so no minion or champion can carry it. The radius of explosion is increased by a value (35%?) The bomb explodes 1 second later.

Other: Time Warp SFX is applied when cast on a bomb, the bomb is visually altered when said combo occurs.

This way Zilean has access to safe waveclear and clever, telegraphed harass that is gated by mana.
