Coming back after long periods of inactivity

I was wondering if there was anything in place to help people who have had long periods of not playing to get back into the swing of things? I have not played in months and feel that should I hit the PvP scene I will be horribly outclassed. And bot games really are no help at all. So is there a good way to gently ease back in or am I stuck on level 30 games?

If there is not, then what would the likely hood of riot implementing such a thing? Such as having your level halved if gone for 2+ months, or perhaps the option of playing maybe 3 lower tier games to get re acquainted.
