To Those of You Complaining About the Lack of Keystone Diversity...
...You can stop now. Just pay attention to PBE. Riot is already aware that they messed up with the keystones and are buffing most of the keystones. These changes happened 14 days ago and you're still complaining? Seriously, stop complaining already. Here are the PBE Keystone changes:
Deathfire Touch (Ferocity, Tier 6)
- Bonus Attack damage ratio increased to 60% from 50%
- Ability Power ratio increased to 25% from 20%
Fervor of Battle (Ferocity, Tier 6)
- Bonus Physical damage per stack based on level increased to [1-12] from [1-8].
- Max stacks lowered to 8 from 10. (Before you complain about the stacks being lowered, 12x8=96, 8x10=80. So it's actually quite the buff; easier to stack and more damage)
Warlord's Bloodlust (Ferocity, Tier 6)
- Now heals for 5%-25% of damage dealt based on level (from 15%) and grants 30% attack speed (up from 20%) for 4 seconds.
EDIT: Stormraider's slow resistance is down to 75%. Sorry for the error in the text. Thanks to xApexPredator for pointing this out.
Stormraider's Surge (Cunning, Tier 6)
- Movement speed bonus increased to 40% from 35%
- Now also grants 100% slow resistance for 3 seconds
- Time frame to deal damage increased to 2.5 seconds from 2
Bond of Stone (Resolve, Tier 6)
- Now [+4% Damage Reduction. 6% of the damage from enemy champions taken by the nearest allied champion is dealt to you instead.] from [+3% Damage Reduction, increased to 6% while near an allied champion. 6% of the damage from enemy champions taken by the nearest allied champion is dealt to you instead.]
- Base damage reduction increased to 4% from 3%
- Damage reduction no longer doubles while near an allied champion.
Strength of Ages (Resolve, Tier 6)
- Now "After reaching the max bonus, these kills instead restore 6% of your Maximum Health" from "After reaching the max bonus, siege minion kills restore 100 Health"
- Effect now triggers on large monsters and siege minions rather than only siege minions.
- Max bonus kill effect now restores 6% maximum health from 100 health.
