Another thing that annoyed me greatly, arguably the most annoying thing in general is the entire disregard for the present time story line.

I know that not everyone enjoyed this part of the game, but it was actually a major part of what got me and kept me interested in the game in the first place.

The present day templer/assassin conflict was interesting, but after Desmond died in 3, the whole thing ended up being pretty boring, bland and lead nowhere. Very sad.
