Locket Change on PBE: explination

[Active] Active changed from an aoe shield effect to to "After a brief delay, creates a protective field at your location for 8 seconds. Allied champions within the field are dealt 35% less damage (90 second cooldown)."

from what i understood, this is a nerf to adcs and squishy champion in general and a buff to bruisers explination:

right now locket depending on who you build on can give something like up to 1k hp shield 1k bonus shield increases an adc's hp by 50%

with this change however, it's going:

• to give 35% damage reduction which is already a nerf to squishy champions and a buff to tanky champions -to have a delay so you can't instantly shield someone from an assassin -it's going to be stationary AND around your position

so say you're alistar who wants to engage, and you engage, if you create a locket field at your position and your adc gets dove, if the adc tries to kite he's going to run away from the field while before the shield would just shielded damage anyway

that's the important aspect of this locket change, adcs can't run back into the field if they want to kite bruisers will be able to run into the field and stay into the field to damage tanks while getting a whole 35% damage reduction against marksmen

additionally one last change is true damage will not get shielded anymore and there are more melees with true damage than adcs the only one who can deal a huge amount of true damage is vayne have true damage for instance and don't forget that the new rune will convert 20% of your damage into true damage!

so... new keystone+new locket in the same patch? that's a very good buff to bruisers
