ap item changes

3 top item changes:

1. 10% cdr on many items w/ 10% cdr unique passive
2. morellos stats deleted, liandrys stats copied to morellos and trades burning for grevious wounds on all ap damage
3. liandrys trades pen for damage amp scaling up to 10% (2%/sec) and now burns for max hp dmg

Minor changes:

1. archangels, rylais, and rabadons are buffed slightly
2. orb of shadows (new) is what haunting guise used to be, haunting guise trades pen for damage amp (see liandrys above)
3. ludens looses all of its speed but gains 500 mana
4. glp-800 looses all of its health
5. void staff nerfed a bit
6. twinshadows readded with 7% ms boost, 10% cdr, and 80 ap

What does this all mean:

1. this is a huge buff to ap DoT or sustained mages, among others should notice a major buff to damage output just from buyiing new liandrys
2. Theres no more mana sustain in primary ap items with the removal of morellos passive
3. cdr is further spread throughout ap items
4. morellos is still a likely rush item for most non Dot/sustained mages although for different reasons.
5. This is also a moderate nerf to all healers since grevious wounds can be procced at all times by all magic damage
6. overall this is likely a minor nerf to burstier mages due to the lowering of the ap on a few items as well as the removal of health of of glp-800, for mana dependant champs this is a further nerf due to complete lack of any mana sustain in most primary buildpaths. Lastly, I honestly dont see how liandrys wont be op on at least brand and morde and it will also significantly shift people like sejuani and amumu from low/middle dps to middle/high dps.
