With the latet Karma updates going around PBE Karma can no longer shield minions.

This isn't the first time Riot took away something the player could use to help the minions.

Soraka, lost the ability to heal minions.

Runik Bulwark (pretty sure I misspelled that,) used to increase minion health regen as well as magic resist.

Banner of command used to increase minion damage I believe. Though I may be wrong, i just remember there was something that increased their damage.

Taric no longer has the ability to heal minions, or give them bonus attack damage. I'm not actually sure his ult boosted their damage though.

I'm pretty sure Heimerdinger's passive no longer heals minions, I know for a fact it doesn't heal towers anymore.

I think the only champion left that can heal minions now is Alistar! And pretty soon They'll take that away too!

Riot why no love for minions?
