anyone noticed people doing more damage they they should be doing recently?

past 2 weeks or so I have been increasingly noticing players doing more damage than they should be doing. Sometimes almost twice as much. Anyone heard of a new hack in the last month that buffs damage without revealing it in the game? I mean people will be doing 2/3 hp damage at lvl 1/2 with starting support items, and be tanker than normal at the same time, so its not like they are going glass cannon runes and masteries.

One particular moment that stands out recently is a graves ult doing 250 damage and killing me when i had 400 hp left... nothing else hit me. the graves was running around freely killing everyone at the start of the game and all game long. A fizz in the same game was also doing that. lvl 6 with 1 item and 100-0 someone 1 level behind in 2 hits, with 1 item. he had Lich bane and boots, didn't use ult, and killed someone 1 level behind him with q and auto. didn't even land e and still 100-0. He ended up going 17-2. sometimes he would do almost no damage, then he would destroy people, then he would 100-0 people super easily the very next fight with no level ups and no item buys.

had a support brand with starting support item take 3/4 hp with 1 e and 1 q. level 2. the other day. I main support and play Brand. he doesn't do that much damage to people lvl 1/2 with 1 rotation. and the hp to damage values in after death recap didn't add up either, just like with the graves I was talking about.

It may just be me, but i have been watching hp and damage values, and they just haven't been adding up in a lot of games lately. anytime they don't, people just snowball like crazy and end up with 15-20+ kills and almost no deaths, and they do ridiculous amounts of damage from lvl 1 that doesn't add up to how much hp their opponents have or what their item/base values add up to. I mean a 250 dmg graves ult that did make direct contact at the very end of its range killed someone with 400 hp left??? Something is seriously off.
