That's not the point that I'm making. My point is that in view of the capabilities of Terminators, why would Space Marine player be crying out for Assault Terminators? If I played Space Marines I know that I wouldn't be, because Terminators are already more than effective enough.
Since you ask, my reasons are these: they have been a distinct unit in 40k for several years or more; they have a separate enough role on the battlefield to call for representing; SGs may not have had the budget to stretch to making Assault Terminator models but a good proxy exists now; less and/or more costly Warhounds in the ‘modern’ SM list will likely slightly reduce the average amount of MWs in the army which can be counterbalanced by slightly increasing the MWs here (and Terminators killing things in combat is more fitting than relying on their allies to do so).
It's a close call and situational but out of the two I think regular Terminators are probably still slightly better overall, due to their greater flexibility in their uses and the fact they can shoot or FF skimmers, whereas Assault Terminators are powerless against them.

This all brings me back to the issue I raised earlier. The original Epic lists should only be altered if there are balance issues or mistakes.
I’m suggesting Assault Terminators deserve to be included in the second ‘modern’ core SM list that is proposed to be developed
as well, separately by those that choose to,
not adding them to the Codex Astartes core list at all. The two lists could and should co-exist perfectly happily allowing
both those who want modern units in a list and those who want the Codex Astartes left as is to be happy

What about an "Epic modernisation project".
An entirely separate (albeit largely overlapping in form) set of lists, balanced against each other, but with no obligation to be balanced against the "classic" lists.
All Epic lists should aim to be balanced to the same level of power, a ‘modern’ list might have more units than the original, but it still should be equally balanced as the old. 40k has power creep in newer lists to sell them more but that element shouldn’t be copied to the epic lists. Balancing ‘modern’ lists only against other ‘modern’ lists only seems unnecessarily limited, undesirable and impractical anyway with the amount of playtesting now.
