DFG was removed about a year ago because it was to good for killing squishies when it was designed to be used for tanks
So here is my idea for a new DFG that is designed for tank killing
80 AP 10% CDR
Active (120 sec CD) Deals 10Xlvl + 100% enemies bonus MR as true damage to the target and marks them with doom
For 4 seconds your MR is reduced by 50% of your bonus MR

alfavhunter1 votesthe item is supposed to kill tanks and have minimal effect vs squishies
and it doesn't negate all MR, it would have a high gold cost (3250?) and be specifically tuned for AP to hurt tanks
Also it could be tuned to instead of shredding MR make you ignore that value of MR for the 4 seconds so it doesn't nerf Galio damage at the time of effect
Yosuke Apperu1 votesStill lol galio is supposed to counter heavy ap. This is a counter to a counter.. It's like someone wanted to put greivous wounds as a thornmail active lol.. I honestly like that cause I do enjoy tanks.. but I realize its bad to make a counter for everything thornmail counters adc's / light life steal, but then mercurial scimitar counters that. lol Sorry I love galio and that's punishing galio for what he does best haha you can make it deal the higher value to the opposite stat.. so if i have 300 armor and 200 magic resist it deals 300 magic damage to me.. idk making true damage universally accessible is incredibly dangerous to do.
alfavhunter1 votesWell it is a suggestion there would be obvoose tuning to be done
For example it could be a 40% shred and it could be the initial damage of 10Xlvl no bonus. So lvl 18 it would be 180 true damage and a MR shred
Even then it would fulfil the role of being a tank killing item for AP
Similar to last whisper for Ad
Yosuke Apperu1 voteshmm... still hurtful to galio... BUT.. nice tuning <3 You wouldnt totally wreck his face in, instead of shred tho make it an ignore, galio loses ap if his mr is inversely effected. So if you shred 100 mr galio loses 50 ap... thats not cool lol
BluePolarizer1 votesIt wasn't used for bursting tanks. The original purpose was to burst squishies. APs with only spells and not sustained damage can never burst a tank with equal gold 1v1. You can prove this mathematically, since a typical late game bruiser, not even full tank, with
has something like 10k effective health against magic damage while even with a total 500% AP ratio with 1000 AP and 1000 base damage, you'll only have 6k damage.
There is no champ in the game with a 500% AP ratio on burst. The only champs that can deal 500% AP in 3 seconds are 
if you stand there and facetank them.
alfavhunter2 votesThe items original intent was to help mages fight tanks
I didn't say it was for bursting them
But fighting them
