Tahm Has A Better TF Ult On A Lower Cooldown
Tahm's ultimate max rank outranges Destiny by 500 units and its cooldown is lower at ranks 2 and 3. I know their kits are apples to oranges, but Its an extremely similar ability that's even more powerful than the original since it can take an ally with it. It even has a nice bonus passive that helps him deal additional damage. TF's losing his niche with this ability being added to the game and he's already pretty weak from the loss of DFG, mana changes (since his sustain was heavily nerfed right before), and weakening of lich-bane.
I think it shows he needs a bit of help here since clearly his kit is starting to show its age with new champions in the works. He needs a bit of love again.
Personally, I'd like to see some of the utility taken off PaC and being compensated with some ratio and damage buffs on the skill along with a remade E that more befits the assassin playstyle he is supposed to give (especially since if your burst doesn't kill your target, they will kill you). What would also be nice is to see is a non-random PAC ordering since the only reason that was added was for when gold card was AoE to round out his RNG reliance (starting gold card can make or break a fight). I'd even be ok with the duration being reduced to 1 second, so long as the damage was buffed up to a solid .7 ratio and given a base above 45 damage. Just...don't touch the minigame aspect. That's the only thing that keeps me playing the champion. I love that quirky mechanic in his kit. Finally, he needs a bit of a mana boost. Wildcards and PaC both take a whopping 100 mana to use!
