Hope this pic helps.
Second as I said again, eots= electro optical sensors in a stealthy sapphire dome, f35 has irst/flir +Laser targeting in a crystal dome.
Another jet can only have irst/flir inside a crystal dome.
Another jet can have a TV camera in a crystal dome.
Another jet can only have laser designated in crystal dome.
And it seems we are not integrating laser pods in our eots.
Mainly, because usefulness of integrating was decided to not be worth it.
Ask yourself, in future wars how useful laser designator will be? How often will it be needed? Even if in few niche cases laser guided bombs are used Why would a expensive manned stealth jet get close enough to illuminate laser to a target to guide the munition, especially when ghatak, cats warrior and other stealth drones are being biult?
One of the jet f35 was supposed of replace was also a10 warthog in CAS(close air support) role, AMCA won't be used for CAS, and f35 is also rarely gonna use it's laser designstor in future due to reasons stated above.
Just don't blindly go for, this jet has it so our jet should have it too, think of the need, benifits, of the system.
Plus even in current world, laser guided bombs have become a niche, and gps, INS guided bombs have become mainstay.

You have a point that UCAV can use LD. But,
> AMCA can also be turned into UCAV/optionally unmanned.
> CATS Warrior IMO is currently a poor design. If not improved, it'll be shot down like a cruise missile.
So sending in cruise missiles worked against poor enemy like Pakistan, could be tough against China.
> Ghatak, like i said before also but you forget, it is boomerang shaped subsonic jet, w/o afterburner, once detected can't defend itself.
> Laser designator is a very small thing in the turret ball of EO pods. Compared to the entire jet, it is like a person carrying pocket laser pointer, nothing exotic or costly. There is no need to depend on another jet.

> 5+gen fighter should be multi-role. No matter how rarely something would be needed, when needed but not there means possible failure. We can't, shouldn't say that AMCA won't or shouldn't be used for CAS, etc. IMO it can & should be the next backbone of IAF.
> The current EOTS shown for AMCA could be just a preliminary one. All they need to do is attach the small laser unit.
> EOTS = F/DLIR/IRST + LDP. If AMCA's EO sensor doesn't have LD then it is just F/DLIR.
> INS, like GPS is a positioning technique. AFAIK both are used together. They're good for fixed targets.
Every guidance system has its own time, place, importance. We have our own GPS but assuming if it is somehow jammed & we need to strike a portion of building or a moving target or in open terrain then either IIR or LGB is needed.
