That's a really horrible assertion, for a few reasons. The first is that Janna's passive Tailwind. While it doesn't look as sexy as other passives, it is the best global passive as the increased movement speed allows your team to harass more effectively early game, allows your jungler to clear quicker, and gives your team a general massive bonus in mobility. Her Ultimate isn't used for the heal as much as the blowback; its a common mistake made by new players that the ult is meant to heal. While the healing component is nice, it is the single best disengaging ultimate in the game and can even be used offensively to blow a person back into your team. Her shield is her primary support ability, but don't disregard the control Howling Gale and Zephyr give you in lane.

All in all, Janna is actually one of the best supports, her kit helps her in bot lane by both buffing her partner and zoning her enemies. It's just that you're not used to it yet.

Right about now Janna is widely considered the best overall support. Has so much utility, can initiate on aggressive lanes and protect passive lanes. Her ultimate is game changing at the right moments, her shields gives a good chunk of AD and protection (Her shield was actually nerfed to break the AD component when the shield broke a while ago) and her movement speed buff is extremely useful at all stages of the game.

janna is stronk

Flashing in and ulting some poor sucker back into my team is a great feeling.

And how the heck is her q and w a shield.

a knock up and slow are not shields. just no.

You are so far out of the loop you have to be trolling.

I wouldn't doubt trolling, look at the username

Troll is useless.

Jerkface.

janna is one of the strongest champs in the game

she is OP w/o the need for items

She's not useless, certainly, but I'm unimpressed by her q. By the time it's charged enough to be useful, the tactical situation has changed enough that the potential targets are dead, or at least have moved out of the line of fire. Any tips on using it effectively?
