well, yes. it gives an advantage that not anyone can get (running more than one client at a time takes a medium computer, not everyone can handle that). also, it was not intended in the game. and, is alt farming allower in other MMO? many of them have the rule "one account, one person".

As a CE buying vanguard soloer with a measly 10 days on my main, my two cents on the issue is that back on the old system the heat for health revive was not necessarily game breaking, but annoying when people spent time that I could use doing FSC or some other run heating off of revives, so I was glad to see that go. I was also apprehensive about the new revive system but I have found it to be better over all, since it means you need to have some skill to do elite and higher ranked missions.
- The spark/emergency revive system really benefits both soloers and group-runners because as a soloer you might die once or twice on a level, and so this way you don't waste nearly as much energy on revives, while as a group player you can run through much smoother as a group because you don't have to waste your hearts on someone else.
- Alt dragging is a problem I could really care less about as a player, though as a developer it would be a huge problem that some people could get ahead easily. I may be isolated in my non-hatred of alt draggers, but if not then proper gameplay should be put above fixing the alt dragging issue.
- On point 2: I usually joined a party for the sake of having more firepower to clear gates faster rather than for revives. (Though I can't say I didn't get my fair share of them from my party).
- On point 4: "Don't kid yourself, this is only putting a damper on party survivability." I'm not sure what was trying to be said by this, but the party with 2 members at 2 bars will have a higher chance of surviving than the party with 1 member at 4 if they are all the same skill level, because while 1 party member of group 1 gets killed, the other can continue to fight, while the group 2 member will die and have to rev to keep fighting, thus increasing party survivability (this is where the heart system comes in handy because the second member can get the other member back up, doubling survival chance|the emergency rev system comes in handy with both groups, though still favoring group 1)
- On point 5: The difficulty part is correct, but the part about sparks leads me to this: Don't suck and you won't waste sparks. If you are losing sparks (even though I believe they nerfed the drop rate since Doctor's reply, this still applies) you may be under skilled or under geared for the area, so you should leave and come back later since elevators are free. (The exception is that P2W guy who buys a shadow key and revs his way through it)
- On point 6: Sparks are less of a money grab than old revive system, because as long as you stock up before a level when you are low, you get off with cheaper revives. On the old system, dieing 5 times in a level left you facing a steep wall for revs, increasing the need for CE, increasing CE purchases. Also sparks drop, thus decreasing the greediness of them. Though because of these points, yes, income may drop.
- On point 7: Think of this as a reward for all the hard work you did finding the shining fire crystals for your 4* crafts. (Radiants are way more common since FSC drops them, and if you do 20 runs a day or something crazy, you can power level your 5* stuff)
- As long as I keep my emergency rev, I am pretty sure they can't mess up the system too badly. I would like to see the health rev feature back, minus the heat transfer, because that is damn annoying. Also, buffing the arcade would be good since there is hardly a reason to bother with changing gates and running it (though they did make a good attempt at this by making treasure vaults not suck and, if my memory serves, there is no mission with a TV in it).
