As a main support player, I have been trying out this new strategy since patch update. Been quite successful so far. (Ancient 1 EU – 6 wins and 1 loss). To maximize heal amount in game. Just focus solely on positioning and some farming early items into full heal potential during team fights.
And the amount of heal you can possibly do is a lot more than you would do damage as pos 4 or 5.
For example last game i managed 53,600 total heal in 45 mins of game.
The strat:
Heroes – Chen, enchantress, dazzle, omni, winter wyvern
Items – Locket, greaves, (Vlads – situational).
Playstyle – farm few items early and position yourself well to not get jumped, buy glimmer if needed. And just heal the hell out of your team!
What y'all think? Open to criticisms & suggestions.
Additional note: some of these support items have been buffed this patch like mek, glimmer, force etc.
