1). The entire point of Self Destruct is meaningless in a game where you respawn, if ships where captureable than Scuttling it to prevent the enemy getting it would have a purpose.
Perhaps it detonates bigger, I don't know. Weird I actually agree with you on something. Perhaps it's just there for the Role players to blow their ship up before they get a new one.
2). Originally Ramming Speed could be used at any time, this led to some fantastic abuses such as coordinated team ramming in PVP when somebody used RSP or FBP. Ramming a ship completely ignores shields and chances are you'll die too thus meaning your Warp core breach will be at point blank too. It makes a far better last resort than Self Destruct. Now that Ramming speed is only available when your hull is 50% or lower it's a good speed boost that can sometimes save you.
There are also DOFFs that make you more resilient when using Ramming speed. Oh and for the record Escorts, some Sci Vessel builds, and Cannon Cruisers are usually head on to their opponents.
1) In theory it explodes more. Timing is indeed an issue though and it isn't an easy thing to test lol
2) This should probably be renamed 'running speed.' It is useful to try to put some distance in if you are in a bad situation. It is occasionally useful in that manner, so although misnamed, it is useful.
Edit: There tends to be an assumption that a limited use or nigh useless ability is replacing something useful. That is often not the case. Sometimes it is there just as a limited use ability.
While I do agree with you in regards to Self Destruct, Ramming Speed is actually quite useful and fun (even after the adjustment that requires a certain amount of damage. It does make me sad to see people using Ramming Speed to run though. In that situation it should cause an automatic self destruct, lol.
Who ever came up with the self destruct ability had an idea and stopped thinking what it could be 10 sec after having the idea.
even if it was instant, it would still be a worthless ability...not even funny. delete that and give everybody a free polarize hull 1 or a tractor beam.
Ramming speed can save you actually, i have to agree here with others, but it is just a divert power to engines button that activates collisions and frees you from snares like tractor beam. They could just leave the colission part away and make it allways activateable, or whenever you're snared (gravity well, tractor beam etc.)
Fleet Support: What ticks me off is that you need to still be alive for about 4 seconds longer after you activate the button in order for the ships to actually arrive. So many times when I know I'm going to die, but press fleet support in hopes of getting some NPC backup to continue fighting for me while I respawn, only to suddenly be destroyed as soon as I hit the button, thereby wasting it.
