Before ppl start to say that not everyone will do savage or that may not interfere in the fights. We just need to remember Alexander Gordias. Back then they make strong dps check that everyone including both healers need to do dmg in other to clear the fight. After the A3 “incident”, they cut the dps check by a lot to make sure that not only players that perform their job on a high level clear savage mode. And now we have the ultimate fight, till they decided to do it again.
On 4.0 this gap increase but tanks and healers still could “carry” a fight, because they could do much more dmg that SE intended to the fight.
In 5.0 with a hard nerv on healers and tanks (specially) damage, and the potential gap on those role decreases. (Still have)
With that the DPS role is the only one that increases and it was by a lot. If you was farming Titania EX in the first week and a half as a tank or healer o even as a dps you probably could feel this gap, ppl could have more than 6% gap before adds with the same comp. I not counting Eden normal because by the time that it was release much more ppl have hit lv 80 (more the time pass, more ppl that will not do savage gets bigger compared to the ones that will try it), and now the gap on Titania can easily pass 10% before adds now. And it was way to soon for me that we hit this gap, the item ilvl potential is still small.
So will they put the bar up and it may become a “wall”? Or they will not force and it will be easy dps wise?
