Morganna changes

Hello. I'm a mastery 7 Morgana main.. I have over 250k mastery points with her. So I have a question about the new changes.. which are listed below.. When it says large minions. Does that include cannon minions.. if not then the "change" was simply a huge Nerf. Her sustain in lane is what makes her so uniques and strong... The fact she can stay in lane longer means she can lvl and get gold faster.. even vs assassins like zed and talon.. who other wise would simply kite her down with no recourse on her end.. it's upsetting enough you removed her spell vamp making her sustain harder especially in the support role.. but now as a support she will be getting next to no healing at all. Unless she constantly attacks the enemy laners.. or qs the cannon minions.. my point is you may have made mid Morgana easier to play against, but support morganna is going to struggle. With far less mana saving ways to heal up.. and with her longs CDs on her shield she needs that gap to Regen health to be ready for the next fight.. I will be fine because I know this champ inside and out. But newer morganna players or new people trying her may struggle .. (Side note as I go morganna jg as well. And do amazingly when my team holds their lanes. Does the updated W/Passive affect healing from the jg camps as well?? And do the medium sized krugs count as large monsters as well?.. clarification wanted please
