But that's the thing again, you're both saying that you shouldn't be punished for screwing up, we've established that players are overgearing content, and you yourself have just posted how overgeared you can get quickly now.
So taking damage isn't a good enough punishment anymore, provided people aren't stacked too tightly Landslides (the only true instakill mechanic in Titan) isn't even an issue at all, it's only 1-2k damage, if that were gone, we'd go back to what i was saying before, content being easily beatable on everyones first attempt, no fun for anyone. The game has been training you to dodge the glowy shit on the floor for 50 levels as well, so the learning curve for dodging has been taught.
As for before when Titan HM was new at launch, well just look at the reward, it was the gate to Coil and your relic, it was specifically designed to be hard. Now it's training wheel content and we've just established that damage isn't enough of a punishment.
So what would your solution be?
Nerf Garuda/Titan/Ifrit EX into oblivion until they're just Garuda/Titan/Ifrit with higher damage? Well, now no one learns a thing anyway, cool.
Increase Garuda/Titan/Ifrit HM damage/HP to be in line with the current average ilvl of the player base? Well now a really fresh player is useless in the fights and no one wants them there because their HP/damage is too low.
There really is no great solution to the problem, short of expecting players to learn the same mechanics everyone else has. I mean, they're new, they shouldn't have to learn or be presented with a modicum of difficulty until they're near the current ilvl cap, right? Your method would just produce an ongoing problem where new players have an easy stroll until they're at/near the ilvl cap and then they're slammed with mechanics that they haven't been trained to handle.
Honestly if anything, it's a problem with the pre-50 learning curve, but I'm sure if there was one before 50, we'd have hundreds of people on the forums complaining it's too hard to get to level 50.
