Hello, i'm Sophie. A Gold Support main from the european West Server.

I tried out Galio Support and in my opinion hes really strong. His pre-levels are reather weaker (1~6) but after 6 he will just start getting his tankyness and destroy enemies. Even though in low Levels hes really strong.

I wont write alot here and will just state what the best Combos are.

Always try to e into their adc and chain it with your max w load, it will taunt them for 1.5s and should be an easy kill for your adc. Always poke with your Q, but dont do it too often cause of eventual mana struggle. Always use your ult on squishies like your adc or the midlane because the ult got an very good damage reduction that many People dont know of.
After you've done your Combo, chain your summoner spell with it.

I usually just go with Ignite because is good at early Levels, but exhaust could be an good Option too. After you've engaged, just exhaust their adc or whenever in fights to peel their damage off.
