I mean, Rakan is kind of like LeBlanc, but a little more utlity-focused. If I have my W and Q up, I can usually kill a carry, and then get out if my team is there or ult through the rest of them and kill them too. If I have my ult and gunblade up, I can usually take on 2-3 squishies at a time and kill all of them -- especially if I have ignite ready. He does a lot more damage than you'd think.
I dont need to "think" about the damages he deals.
I can just do the maths.
Late game Leblanc :
Passive : 300 + 80% AP
Q : 195 + 50%AP
W : 100 + 20%AP
E : 240 + 100%AP
R (+Q) : 400 + 60%AP
it's a total of 1235 flat damages + 310% AP on a 16s CD with 40% cdr.
If we takes a late game lb with 600 AP, it's a flat 3100 dmg on a 16s cd.
Rakan :
Q : 250+50%
E : 250 +50%
R : 300+50%
It's 800 + 150% on a 60s CD with 40% cdr.
With 600 AP it just means : 1700 damages on a 60s cd. (Ok, lets add the lich bane : +50% ap : 2000 damages, still lightyear away from lb if you count cds).
Viktor :
Q : 120 + 20% + (100%AD=~100 late game) + 50%
E : 350 + 100%
R : 665 + 125%
Lich : 50%
Total : 1220 + 345% = 3290 in a large zone. Long range. (harder to hit the spells than with lb tough).
On the same CD as rakan.
So you are telling me you take 3 squishies at a time, and your team couldnt manage to win the 4v2 after you killed these 3 squishies ? Seems quite strange from my pov.
