Small ships considered training wheels, because they are accessible and very cheap, which means when you blow up, it won't bite in your balance as if you blew up in your medium ship. I can easily destroy any ship in PVE, often even 1vs3 in my Eagle, but destroying brainless NPCs doesn't take any skill whatsoever. Mediums and Large ones are just more convenient, as you kill faster, can fight a lot longer and you cannot be destroyed as easily.Also, I don't know if this was you or not but small ships are not training wheels (excluding vulture). Medium ships are training wheels, especially the new ones that don't even require pip management and especially these days when a single mined ore is worth more than most small ships. From medium ships you can decide whether to master FAOFF and go big ships or be a man and go small ships. Vulture, both kraits, and maybe the FAS are the training wheel ships in this game IMO because of less pip management required and excellent pitch speeds, which is the #1 thing new players look for in a ship when they want "agile." This is before they learn to use lateral thrusters. I guess "noob ship" is what they would be called in other games.
Lastly, nobody seriously PVP in small ships, probably because all PVPer are "noobs" and aren't really men...
Actually I posted my Viper IV build in that thread, and stated here (and in several other threads) that it is my absolute favorite ship in the game. Uniqueness of thrusters or flight model doesn't magically makes it better at heavy combat, which argument has erupted here about, it's simply a matter of preference and personally, I do enjoy flying it less weighted. What I'm saying is, it has its role and place in the game, it's just not hardcore combat, is all.Vulture is hands down the best small combat ship. Then it's the courier. Then it's a matter of opinion. But both vipers have boost characteristics that are unique out of all other ships in the game. That's not an opinion.
Just go engineer a V4 and you will see, knowing the numbers in this game is nothing compared to actual flight models.
