listening to msi after match commentary, watching analysts overlooking glaring issue (EDG vs. AHQ)

Kallista building BT first? Thats a glaring issue.

Sustain is crucial on adcs but there aren't decent means of getting it. without completing a huge 3500 gold item .

The reason she didn't do enough damage is particularly because she needed to have a good ratio. her ratio was heavily leaning towards lifesteal stats first as opposed to a good mix of dps stats along with decent lifesteal to complement it. Please see this suggestion There's ample room for the addition of a new greater vamp scepter to allow an adc to keep a good ratio of stats while still hitting a sustain threshold to help her survive.

I would suggest buffing lifesteal quints as they are so not cost efficient compared to attack speed quints. If lifesteal quints become an issue I would suggest doing away with them all together then and buffing items instead. Like it used to be. Its easier to balance around that. Or honestly fix the game around it. Because I really think setting a solid structure/foundation for lifesteal first and basing the game around it is a better way about doing things since no matter what adcs need to be able to hold their own with good ratios of stats throughout the game not just late with full items.

For example with decent lifesteal quints a Kalista could build and reach about 15% lifesteal + 3 from doran. reaching a threshold similar to that of BT's. Whats great about this however is her damage is significantly increased since attackspeed considerably increases her damage output not to mention the botrk passive.

If an adc chose not to build botrk they could instead build greater/grand vamp scepter giving them say 10% up to 12% lifesteal. Now since this would only cost about 950 gold they could follow with IE + zeal + zerkers. This would be comparable to a kalista getting botrk into runans hurricane into zerkers.

I have a long explanation in the works to explain why its a required and not op buff that i will be posted. I just have so much written i don't know where to begin.

Anyways seeing an adc building BT first item should be a red herring to riot. I get it kallista can sort of get away with it. But its mostly a solo q thing not at that level of tournament play especially vs two cinderhulk tanks.
