It is if Cassandra's the main thing you care about
For me:
"No Cassandra, no Inquisition, no game."
Really, the biggest point for being an elf is more relevance to the elvish stuff later as the player. Humans get that elsewhere for pretty much everything else actually going on with the plot of the story.
There's not that much bonus content there in the Solas side, he simply tells you some elvish stuff you wouldn't have heard playing the game otherwise. There's barely a difference between the two as far as their merits are concerned.
This game's too easy as it is for me to give a dang about racial abilities and such, so no comment there. Beyond the extra skillpoint is nice, lol.
Well Its typical for humans to be that way, its not like I was denying that.
Elves have a lot of unique stuff in DA:I. For example making the life of elves better which includes elves becoming nobles, alienages going away etc... can only be done by an elf Inquisitor who puts Briala on the throne as "shadow empress". The relationship between Briala and the Inquisitor and Inquisition keeps the stability but if you are not an elf nobles will rebel and elves will never get these changes. Its very significant.
Then there are events of Eluvians, elven gods being real, Mythal helping you to defeat Corypheus etc... I mean lets just take look at major events that elven gods have done so far.
Saving the warden at DAO
Saving Hawke at DA2
Solas Salves the Inquisitor from dying due to mark
Solas saves the Inquisition itself by leading it to skyhold
The aid of mythal is necessary to defeat Corypheus
Its as if they are pulling the strings and the fate of the world is decided by them.
