I'll try and give a detailed answer here
So while I get where you're coming from, roughly, I would say in the modern game you can have a variety of players, often a combination of forwards and backs. Sinckler/Furlong have lovely hands and use this to vary their games well as an example. However the ability to throw a ball out the back of a hard line, or a soft pop pass to said runner is often the most a forward needs to do, because they have enough distributors to fling the 20yd passes around with the backs in the pod
So tipuric being bale to kick/pass doesnt mean the team will be more attacking. Front foot ball, from soft shoulders, offloads and good running lines allow a high tempo game, creating space, allowing scores to happen and some sexy rugby. This is a fundamental of the sport. Tipuric on the pitch will not give me the go forward, game breaking dynamism of Watson & Curry. He's a very talented player, but Plan A can change in terms of not just hitting one out runners etc.
Quite often again, it's about moving the targets around, so not just playing one out off 9 and truck it up. Having those tip ons, out the back options, to create little hesitations and space on the gainline from the defense. So plan B isnt just "chuck a forward on who can pass, or run fast, or kick", its change your style, to maybe using the kicking game more often, allow the freedom to release offloads, demand less structure if the ball is available at a ruck, just play it, etc. Tipuric as a versatile attacking option will not change the style of the game, and is also less llikely to win a turnover or break a tackle and get me up the field. However if you go a 6/2 split, hed be a great man in 21 shirt. Because he can play on the wing if needed, as per usual
In summary, a team of distributors doesnt make you a great attacking team. Its about balance, go forward, ability to recognise opportunities and take them (usually from the backline because they are scanning the defense more often, due to a lower carry volume, in particular 9/10). England are a prime example when they ahvent had Manu around, they've struggled to penetrate a gain line, and thus looked impotent
I'd also say doing a disservice to Watson and Curry. They dont do Billy and just run straight, they run strong lines, at pace, and are very powerful, enough to push through any slightly weak shoulders.
