Sindh, the 2nd best India contender, which isn't that great.

So, I started as Sindh and was able to puppet Kalat, I think Puppeting might be the best early game because that damn imfamy adds up soooo fast. I save scummed until I got at least under 15 infamy for conquering the 1 province minor at the start. And then, well, that was it. I really got nothing after this, I have a theory that if you attack Afghanistan when they attack Russia, you have a shot, or when they're dragged into it by an alliance war. But that happens before you're actually able to get the two countries that border you. So that means a very long truce, with the British bordering you. You get britished far before their truce end. What in the hell can you do? No china pop exploits, or any real allies you can do. I once got an alliance with Panjab, which they offered, ONCE. I thought about possibly going for the Saudi area states(Oman or Abu Dhabi), but they usually have a stronger navy(Strong as in 1 extra boat made of sticks probably), or if you're lucky they don't, but tough sh*t they have a stronger military. I want to play sindh, because it's tough. But I am outta ideas.

Getting sphered is probably your best bet, but the only way to influence that is by improving relations. Russia? Ottomans? UK?
I'd go for ottomans because they're easier to break away from later.

I would suggest waiting until you have a few reforms to annex the Baluchi minors, which would hopefully allow you to westernise faster.

To be honest, I think you're going to have to wait a bit, probably up until a Great War to do anything against the UK. Maybe trying for an alliance with Afghanistan which you can then use against Persia would be worth it?
