Cassiopeia Rework By The Numbers
So I have seen a lot of people recently talking about how Cassiopeia does no damage after the rework but I haven't seen a real comparison between the two accounting for her types of play style. That said I'm creating this thread to show the math of just how much damage Cassio did pre-rework when maxing both Q and E starting at 39 AP level 2, then level 6 with 100 AP, level 13 with 500 AP, and then level 18 with 1000 AP. Also note because there is no way to account for the duration of how long Miasma will effect a target I'm excluding it from these calculations.
For reference Old Cassio numbers Q--75 / 115 / 155 / 195 / 235 .8 AP scaling E--50 / 85 / 120 / 155 / 190 .55 AP scaling all ranks R--200 / 325 / 450 .6 AP scaling
Pre-Rework Cassiopeia Q max Level 2 with 39 AP Q--106.2 E---71.45 Q+E = 177.65 Q+Ex2 = 249.1 Q+Ex3 = 320.55
Level 6, 100 AP Q max. Q--235 E--105 R--260 Q+E = 340 Q+Ex2 = 445 Q+Ex3 = 550 Q+Ex3+R = 810
Level 6 100 AP, E Max Q--155 E--175 R--260 Q+E = 330 Q+Ex2 = 505 Q+Ex3 = 680 Q+Ex3+R = 940
Level 13 500 AP both Q and E max rank Q--635 E--465 R--625 Q+E = 1100 Q+Ex2 = 1565 Q+Ex3 = 2030 Q+Ex3+R = 2655
Level 18 1000 AP Q--1035 E--740 R--1050 Q+E = 1775 Q+Ex2 = 2515 Q+Ex3 = 3255 Q+Ex3+R = 4305
For Reference New Cassio Numbers Q--75 / 115 / 155 / 195 / 235 .45 AP scaling E--55 / 80 / 105 / 130 / 155 AP Scaling per level .40 / .45 / .50 / .55 / .60 R--150 / 250 / 350 .50 AP Scaling
New Cassiopeia Level 2 Q--92.55 E--70.6 Q+E = 163.15 Q+Ex2 = 233.75 Q+Ex3 = 304.35 Q+Ex4 = 374.95 Q+Ex5 = 445.55 Q+Ex6 = 516.15
Level 6 100 AP Q Max Q--200 E--95 R--200 Q+E = 295 Q+Ex2 = 390 Q+Ex3 = 485 Q+Ex4 = 580 Q+Ex5 = 675 Q+Ex6 = 770 Q+Ex6+R = 970
Level 6 100 AP E Max Q--120 E--155 R--200 Q+E = 275 Q+Ex2 = 430 Q+Ex3 = 585 Q+Ex4 = 740 Q+Ex5 = 895 Q+Ex6 = 1050 Q+Ex6+R = 1250
Level 13 500 AP Q--460 E--455 R--500 Q+E = 915 Q+Ex2 = 1370 Q+Ex3 = 1825 Q+Ex4 = 2280 Q+Ex5 = 2735 Q+Ex6 = 3190 Q+Ex6+R = 3690
Level 18 1000 AP Q--685 E--755 R--850 Q+E = 1440 Q+Ex2 = 2195 Q+Ex3 = 2950 Q+Ex4 = 3705 Q+Ex5 = 4460 Q+Ex6 = 5215 Q+Ex6+R = 6065
To compare this
Level 2 39 AP Old Cass - 177.65--320.55 damage per Q with damage depending on number of Es hit New Cass - 163.15--516.15 damage per Q with damage depending on number of Es hit
Level 6 100 AP Q max Old Cass - 340--810 damage per Q with damage depending on number of Es hit, final number includes ult. New Cass - 295--970 damage per Q with damage depending on number of Es hit, final number includes ult.
Level 6 100 AP E max Old Cass - 330--940 damage per Q with damage depending on number of Es hit, final number includes ult. New Cass - 275--1250 damage per Q with damage depending on number of Es hit, final number includes ult.
Level 13 500 AP Old Cass - 1100--2655 damage per Q with damage depending on number of Es hit, final number includes ult. New Cass - 915--3690 damage per Q with damage depending on number of Es hit, final number includes ult.
Level 18 1000 AP Old Cass - 1775--4305 damage per Q with damage depending on number of Es hit, final number includes ult. New Cass - 1440--6065 damage per Q with damage depending on number of Es hit, final number includes ult.
There is a re-occurrence at pretty much all levels and amounts of AP. For Twin Fang 1-3 Old Cassio did more damage, however, new Cassio is about to get off 6 Es in the same time old Cass got out 3, this caused her top end damage to be significantly higher at every point of the game. The bottom line is Old Cassio did more damage with less Es, but as long as New Cassio can get at least 4 Es she will out damage the Old Cassio in every 1v1 scenario.
Now having said and done all of this I hope to turn this discussion away from the myths that "New Cassio does no damage" and focus it more on issues of her theme, IE losing her poison mage feel, and also how riot could make some adjustments to her current kit that could enable her to regain that feeling and perhaps make her kit more open to all players. My person opinion right now would be to make the following change to her passive...
Aspect of the Serpent Cassiopeia gains a stack of Aspect of the Serpent for each second that an enemy champion is poisoned, for each poisoned unit that she kills and 1 stack when she hits an enemy with Twin Fang per poison effecting her target up to a max of 400.
This would allow her to gain additional stacks when a target is effected by bother her Q+W but also give her team synergy with Teemo/Singed/Twitch, so for example say a target is effected by Noxious Blast, Miasma, and Twitch's passive Cassio would gain 3 stacks total per E she hits that target with. It's a small change but I feel it could make a big difference in opening up the champion to those who are currently having issues achieving the 400 stacks and it furthers her interactions with poisons, albeit not necessarily in a straight damage/debuff sense that others may be looking for.
