I can't say I agree with you, and I am happy the way things are designed right now. I see no reason why raid gear has to be the "best" gear without any alternative. Not everyone raids... and before someone says something asinine like "if you don't raid why do you need high ilvl gear?", every player, regardless of the content they prefer to engage in, wants to progress their character power. What content you choose to use that increased power for is IRRELEVANT.
I see no logical reason that raid gear has to be the "best" gear. Is raid content challenging? Sure. Should it be rewarded? Indeed it should... and it is. In fact, raid gear uses unique models found nowhere else while it is current content, so raiders have a way to "show off" their accomplishments. Does the fact that there are alternatives of the same ilvl diminish those accomplishments? No it does not. Why people get so hung up on what other people have is something I will never understand. What gear someone else has access to has no relevance.
Tomestone gear is the "slow and steady" way to acquire gear. It also benefits raiders when rng doesn't go their way or when a static prioritizes one role over others for drops. Ultimately that's the model SE went with and continues to go with, and frankly I am glad of it.
Know what makes SE think everyone should have the opportunity to get similar ilvl gear? Because they aren't looking to foster a raid or die environment and put raiders on some sort of lofty pedestal.
Ultimately SE decides how to design the game. We can give our feedback as we like, but that doesn't mean they have to agree or accommodate us. We speak with our wallets to let SE know what we like and what we don't after giving feedback. And while I can't claim to know the hearts of every player out there, I have a strong suspicion your opinion is in the minority. Don't like how SE decides to make gear available? That's "tough".
