Learn English – Has always been and forever will be valuable…(phrase)

Any of these should work:

• I have always trusted you; and hopefully, I always will.
• I have always trusted you. And hopefully, I always will.

This is more dramatic/emphatic: (and more common):

• I have--and always will--trust you.

You could also say this:

• I have always trusted you. And hopefully -- if you don't rob me or stab me in the back -- I always will.

Even though we are not sure what idea you're trying to express, we can say that you're using the phrase not quite idiomatically in that sentence.

as it has always been reaffirms a previous assertion about the state, condition or quality of something and adds the idea that it has always been so.

This elevator is broken ^state, as it has always been. From the very first day it was installed, it has never worked.

This road is crowded ^state with truck traffic, as it has always been. Truckers use it to avoid the tolls on the interstate.

Mining today is a dangerous ^{condition/quality} occupation, as it has always been. Unless the mine is adequately ventilated, explosions can occur.

You must be able to carry forward, so to speak, the predicated state, condition, or quality from the earlier assertion:

...as it has always been [broken]

...as it has always been [crowded with truck traffic]

...as it has always been [dangerous].

In your conversation, however, there is no reference to a state, condition, or quality. The statement to which you're replying says:

You are missing a lot of great games.

You might reply:

... as I always have [missed a lot of great games]

P.S. As FumbleFingers remarks in his comment, as ever would be an idiomatic reply (I think moreso in British English than in American English, where we would say as always).
