I see something unusual or strange...well not right, just...."unfair"

All the latest champ crated from riot games are mage or jungler:

Zyra > mage

Diana > mage/jungler

Rengar > jungler

Kha'zix > jungler

I start playing when zyra was released, so i don't know previous released hero.....but, well, the mean of this post is simple: when the next support champ? Or maybe an ad carry like ezreal or corki? When the RIOT have released champion with this features? If someone can link me some site i will be very graceful to them XD

Thanks for the attention, your match start right now
