Was the trial a mistake?

So, as background, a while ago before Andromeda was released EA launched an essentially free trial in which you could play ten hours of the game.  Now, from a marketing perspective, this makes perfect sense.  They were tring to build up hype for their work and show it off for people who were still on the fence and wanting to buy it or...not.  But, at the end of the day this decision seems to have backfired, because the more I read these forums, the more I realize that people were turned off especially because of the trial.  And I think this boils down to one simple problem, and that was that they limited what people can do during the trial.  

Now I do understand the reasons for it, they did not want to have major spoilers for the game running around before it was even out.  This was a good thing.  But, this set up people having very different experiences within their ten hours.  In my first PT of the game after ten hours I had already done what was, for me, an extremly fun experience.  I had already played through A Better Beginning, which I thought was amazing, recruited Jaal, which is something that is always a priority for me in my BioWare games is to make sure I have all my companions recruited ASAP, and I had either ten a Tial of Hope or was well on my way to doing that quest.  But, for people who did the trial, they were essentially limited in their ten hours, from what I have heard, to Eos.  And they could not get into the Vault.  They were stuck.  Having to grind on pointless side quests and a lot of meanial tasks, which from one perspective makes a lot of sense but it if I were in their shoes I probably would have been greatly frustrated.  Not enough to not make me want to buy the game, or even not love the game, but enough to have a frustating experience.  
Because I realized I had this problem with BioWare's last title, Dragon Age Inquisition.  Which, while it is my favorite game of all time, the first nine or ten hours in my first PT of that game was deeply frustrating and it was beginning to look like a Tier 3 game...at best.  Which for a BioWare game, is very dissapointing.  But then In Your Heart Shall Burn happened and the second act was much, much better and subsequntly my other PTs of the game were a lot funner because I knew what was in store after I got through the grinding.  But, MEA wisely removed the power requirement in the game so you could do what quests you could do for whatever reasons you wanted to in whatever order you wanted to do them in which greatly enhanced the experience of the main game upon release...but the trial was stuck behind an artificial gate.  They were stuck in the Hinterlands.  For ten hours.  Without the ability to advance the story to the good bits.  

Couple this with the fact that the Trial was, apparently, less polished then the release version which was already a...mess...and it is actually  abit more understandable why the game was recieved the way it was.  EA and BioWare had a golden opprotunity to showcase the game's strengths, of which there are many, and instead focused on the opening area which involved grinding tasks and side quests only, not the amazing story and RP opprotunities I felt the game provided.  

Of course the main problem here, and the frustrating thing is I am unsure how to fix it.  EA was driven by very smart marketing decisions, but it backfired dramatically.  So other than the idea that they should 'get gud' I have no other advice to offer.  

What says you BSN?
