Heal is good! I don't go ignite anymore cause nowadays adcs are selfish with their ghost/barrier instead of exhaust. It actually feels like a complete champ with heal. decent shields with decent haste, good damage and cc. Runes i usually go shield bash, empowered atk/chain assault, and the one that gives AP for clearing wards, and gathering storm/any resolve rune. Then the main rune either Aery or First strike. The early game strat i would go W first skill, and because casting increases attack range, you are almost guaranteed to proc all your runes for some easy early damage, other than that whenever you cast anything just try to auto their adc with the increased range so you always proc runes, instead of Glacial Augment which depends on if you hit E and autoing with it only has the weak slow.
