For that matter, the F-14B struggles, but its not because of the weakness of the BOL pods. Rather, its the fact that the opponents have access to better missiles, really forcing it to play extremely defensively. The Phoenix can be fun, and at times gets you a kill even in an uptier.
Its that the only missile useable at such a high BR is a missile that is doctrinally outdated, besides being the worst SARH missile.
The F-14B struggles from the same syndrome, the Me-262s do: too good for a lower BR, to bad for a higher BR.
Thats why most people play the F-14A, or the IRIAF Tomcat or the F/A-18A - a more forgiving BR for the capabilities of those aircraft.
As for the Harrier: not all planes have to be good at ARB. If I have a plane that fills a niche role, or it is good in GRB whereas struggling in ARB, Im still okay with that - I can still have fun with it.
Tornados… well. Iconic, and underwhelming, suffers the same problems that say the Mig-21s can suffer from: the ADVs/ Fighters were always more interceptors than air superiority fighters, and their main target is missing. Dont get me wrong I still find enjoyment from my Mig-21s.
