There no way Enton is stronger than Amaterasu.....Amaterasu is obviously faster than Enton.
A needed to go in his V2 in order to just dodge Amaterasu.....Garra sand was enough to block Enton in time so unless you're saying Garra's sand is faster than A in his V2 then you should stop this.
gaara's sand has shown the ability to block an explosion the instant it explodes,so it can guard against amaterasu,and the sand that blocked those flames were from gaara's reaction time,not his auto sand. Also gaara blocked 3 entons at once vey easily,so it's on par with amaterasu. Also if sasuke blocked enton,why did sasuke claim he himself guarded using enton?,and since enton makes use of already existing flames,which flame did he shoot gaara with that was alreay existing?,he never used enton offensively while in ms,he only used it to defend himself.
Gaara already blocked A's v2 strike while simultaneoulsy blocking the enton underneath at the ame time seconds befroe they touched despite being accross the room.
Amaterasu isnt stronger than enton,they are both the same,only difference is shape manipulation,enton makes use of the flames of amaterasu,so the strength is the same,kakashi said that when someone adds both nature transformtion and shape manipulation,their attack power increases greatly,well amaterasu is nature transformation(katon of the hghest level),then enton adds nature manipulation,so enton is actually stronger than amaterasu.
Blockin and dodging are differnt things,gaara dosent need to dodge it,bee managed to block it with his tentacle IIRC,so gaara can too.
Back on topic,
piercing attacks are no longer gaara's weakness,people saying sasuke's chidori will pierxe it are wrong
in the SRA arc,kimimaro's cs2 bone spear was stroger than sasuke's chidori,he not only tried to pierce,but drill through the sand,yet it didnt work,chidori isnt piercing his sand that stopped A in v2 who had raiton on him.
People tend to say that his raiton armour dosent offer penetraton,but that is wrong,raiton techs when used offensively offers 2 things,speed and penetration.
Raiton armour does not increase your physical strength,but your speed and reflexes.we know that the raiton chakra interacts with the environment as it deflected sasuke's sword.
When he used a liger bomb,he used pure strength,as he didnt hit him with any body part,rather simply powerbombed him,that was pure force,
when he went v2,karin calculated his power to be bijuu level,a chop from a standing position broke the susanoo,his strength doesn't increase,and a liger bomb is obviouslt more powerful than a simple chop,so how did he break it so easily?,simple the raiton shroud boosted his penetrative power to the point where a chop broke through,now we have a downward kick,which takes advantage of the gravity to boost the physical power,then coupled with v2 shroud,is a stronger piercing and physical attack than a cho,and gaara blocked it asily whil blocking spikes of amaterasu from below at the same time.
If gaara bloced a bijuu level penetrative attack,one from sasuke isnt a problem.
