Cause Xulos is an OG plotter, and Serkan just showed up and acted all powerful. For gameplay? Because 90 nora for Dark Favor 3, Death Pact, and Tariff fits into way more BGs than a 100 nora ranged buttercup super champ.
You mean serkan showed up threatened xulos and he was all like oh okay i'll be a little coward now. Serkan FTW xulos a *****boi Serkan cant do much more than tap and run away. Xulos is an absolute monster on the other hand however.
Serkan needs surge lich again, is very risky wait fuel with vendetta, remember: 1 champion die for 1 dmg, is a bad Investment.
It does mean his damage is awful outside of liches though. And if you're using him in liches, you instead have the problem that liches are garbage.
12 damage at 6 range isn't really garbage. on top of vengeful stacks pretty quick in FW. also liches aren't that bad they just crutch heavily on leverage and range spam
What the heck do you expect for a teleporting, 7 speed unit? 15 DMG? 12/6/Vengeful/Siphon is more than plenty. Surge is a piece of crap anyway.
I don't like the ability in general, on a lot of units. It's been passed around a lot. In this particular case, I think you're trading off a ton of later-game damage and versatility for a tiny boost in a junky theme, so it's also a bad upgrade, even in Liches.
Assuming I'm using Liches (cause all upgrades are BG dependant and this may be less true if someone else is running a different list) I'd be jamming at least a couple non-Lich units, for a couple reasons. First, the actual Lich pool for a couple slots, namely durable, cheap melee, is tiny. Second, FW has a ton of abusive stuff that is both abusive and synergistic. So even in a Liches list, I'd run at least 1x Death Guard, 1x Dusk Creeper, and 1x Bile Zombie (because Necro Hex is especially good in Liches). Death Guard and Bile are built to die. By running Vengeful over Surge, Serkan gains more stable damage with much higher scaling. I could see a case for Surge because it has a higher kick early, and because you might want to approach early and mid-game differently. But at least the way I would approach building Liches, I think Vengeful is better.
