So, in a nutshell, because you're struggling to beat this part of the game, you think it's not fair and therefore the loot should be easier to obtain? This mentality speaks volumes about the fundamental problems with Destiny and the community.
lets get this straight, you're not beating the game, you're beating your fellow opponents.
This is a player vs player competition, so you beat your opponents. In a pool tournament you beat your opponent, not the game of pool.
With regards the loot, I've done quite well so far. I've got 3 pieces of armor, 3 weapons, the class item and the shader. Given the right map and the right group, I'll get to the lighthouse, and do so without paying to be carried there as some people have done ! My issue here is not that I'm struggling to get the loot.
The issue here is that in most competitions where you play against other teams, there is some form of ladder or skill base match making to ensure you play against players of somewhat equal skill. You can argue that as this is the "end game" PVP content, there is no place for those with less skill. You win the premiership, or nothing. There is no championship, or Division 1 or 2 title to be won in the trials of osiris.
These people will argue that the scrubs not good enough to go 9-0 in trials should play crucible. Which is a bit like arguing that if you're not good enough for the premiership, you should go play with the kids in the park. Iron banner is like playing with other adults in the park. There's not really anything in between.
Destiny is in a unique situation here, because its very much a gear based game, like an MMO. Your gear isn't all that matters, but it will make it easier or difficult if you have the wrong gear. Equally choosing gear that you have, that others can't get that will give you the edge, is perfectly fine in destiny and goes against the whole cornerstone of normal FPS games like COD or CS where competitive games are based upon everybody having the same weapons.
But if you look at the other online PVP competitions outside of the FPS area, these usually have skill based match making (ie league of legends) but destiny has none.
The issue that I see it, is that trials is destructive to the community. Those that are issuing the beat downs to the other players, love it and think its the best thing ever. Those receiving the beatings will just stop playing and give up. Meaning that ultimately, not very many will be left playing trials meaning it only serves the top 1 % of PVP players.
To be specific, Destiny has some 16 million players, of which 188,000 got to mercury on the first weekend. That's the top 1.175 % of players.
By comparison the level 35 prison of elders was defeated by 900,000 in the first 3 days. So around 5 x the completion rate given similar 3 day time frames on the opening week. I would make comparison to the crotas end hard mode completion, but can't find any stats. I can find vault of glass, but these seem unfair since the vault was openend at a point when most weren't high enough level to attempt it, and the player base was much smaller making the % comparisons unfair.
