[Assassin's Creed] Why are the modern day assassin's so rubbish.

Ezio, Jacob, Conner, Edward, Evie et al were all prepared to use whatever means necessary to achieve their goals, from business to politics to criminal networking. 

Coming in to the modern day, the templars have grown with and helped to create the modern age, mostly through abstergo. We have hitmen for hire that can kill you by putting radioactive substances in your dinner.

Yet the OG Assassins' modern descendants consist of some barely featured grunts that just seem to die a lot, a possible double agent and two nerds that are all pinning their hopes on a bartender learning ~600 year out of date skills.

That wasn't always the case.

It used to be that the Assassins were a major player on the world stage. Sure, they weren't as public as the Templars, but they were evenly matched in terms of power and influence. Do you want to know where the headquarters of the Assassin Brotherhood was in the late twentieth century? A skyscraper in Dubai. 

Then the Great Purge happened. In the year 2000, Templar sleeper agent Daniel Cross murdered the current Mentor during his initiation into the Assassin's inner circle. What ensued was a global crackdown in which the Templars used the disarray to destroy Assassin cells across the world. By the years end, the Assassins went from clandestine secret society capable of deciding the fate of nations to a fragmented network of resistance fighters. 

The modern Brotherhood isn't the result of Assassin ineptitude, but a brilliant power play by the Templar Order. The Assassins aren't a ragtag group of misfits by choice, these are just the ones who either survived the purge or were late to the party.

Also, many additional materials show that the Assassin Brotherhood is quickly rebuilding. They've reorganized, reestablished cells across the world, and have managed to go toe to toe with Abstergo directly and win. They may be a shadow of their former selves, but they're hardly rubbish.
