DDO is easier than it's ever been. There are more free to play quests than in 2009. There are more free classes and races now than 2009. A subscription costs the same as it did in 2009. The bar of entry is lower than ever before for new players to try the game out and level a character to 20 or 32 and get a sense for whether they like "chilling" with the game or not.
It's not logical to assume a new player would automatically be unwilling to endure the same issues you see as detrimental and end up exactly where you are now - spending a lot of time on the game and having fun doing so.
So what's the problem with telling them up front what those issues are and letting them decide for themselves if they are "unwilling to endure the same issues you see as detrimental" without spending hours to get there? What assumptions are you making that the bar is low to get to 20 or 32 moreso now than ever? That the new player will buy a sub to a "f2p" game when they realize they can only open normal and even if they feel like repeat grinding the same free dungeon to level to unlock higher difficulty that doesn't drop any relevant named gear and you have to be lucky with random gen loot only to find there is not a lot of free quests once you hit around level ten? Then what? Buy vip, buy expacs to progress? All to get to 20 or 32 to "get a sense for whether they like 'chilling' with the game". Can it be done? Sure. It's done on HC every season, a vet will know how to do it, how many times is optimal to run kobold's new ring leader for best xp gains, how to deal with the bugs, the lag, but a totally new player with ZERO knowledge in a game that hasn't aged well and has a huge paywall for content compared to other products on the market? No, they will not know the "tricks" unless they have someone there taking the time to show them, carry them, hold their hand, what have you. Will such a totally fresh newbie make it to 20/32 without support nowadays? The game's player retention rate/new player retention rate will tell you that.
Who said everyone here is spending a lot of time on the game and having fun doing so? You. You are making assumptions that everyone has the same motives and experience. We are all here enduring the nerf cycles, the lag, the grind, the inventory bloat. Why? For friends we met along the way, for goals, for sunken cost, for so many reasons? Does that mean nothing should change because everything is perfect as is? No, hence the survey. Why would ssg offer a survey like this if not to ask "how do you (the customer) think we can do better". If I received so much negative feed back to a customer survey at work that would be a big red light of "something is seriously wrong and we need to sit down and rethink some policies".
