Love how you used me there -- it's what I get for that Bragging Thread post, isn't it?
Seriously, though, it is a good example of stun-lock in RNG. I personally think the stun effect is overpowered, though I can't really point to any evidence to support my theory - it's just going by the old eyeball test. And while Flatline's stats in that example are woefully low compared to RMS Pieztanic (particularly in regards to COU, which brings up another point to me, but I'll get into that below), I still can't help but come away with that feeling. I've had missions where my characters have actually lasted a few minutes before getting stasis-locked (rare, especially compared to much more often I'm instant target by every Autobot in sight in missions, but that's yet another issue I have with RNG), but one ram within the first minute stun-locked my character so badly that they never got to do anything before being taken out anywhere from 3-5 minutes later in the mission).
This leads into the first point I have: I still can't help but feel that COU is more important a stat than people give it credit. I understand SPD governs your to-hit chance, and I get that STR boosts damage while STR+END incorporates armor for damage mitigation, but COU seems to govern (again, total eyeball test here) how many times you get to attack in a mission/arena match. And seeing those 1-10 and 1-11 missions... maybe I'm exaggerating here a bit, but I feel like at least 85-90 percent of all attacks in those missions are your high-level (level 8+) characters. Of the remaining percentage points, I also come away with the belief that low-level (levels 1-3) actually get given more chances to attack than the mid-levels (levels 4-7). Again, straight eyeball test here, no real evidence to back it up, so your mileage may vary.
I think the only "gripes" I have with the RNG of the game, though, actually stems not from any combat stat per se, but two things:
1) the plethora of what, at least to me, doesn't pass the eyeball test for overpowered weapons (I have characters with 7 tons of Iron and 6 END who can
still be one-shot by 10/10s like Fusion Cannon, Dreadnought Missile, Magnus Hammer etc. Mind, I know Iron is crap for damage mitigation, but so is everything else through at least Rank 3 (it's sad that I think Iron is better than Vanadium-Steel, even though I remember that U238 used to be considered halfway decent back in the day for low- to mid-level characters). Even when I do survive a single shot from those 10/10s, I'm almost guaranteed to get hit by another shot within seconds, usually by the same character, which leads to my second gripe...
2) INT is bass-ackwards.
Intelligence: Learn certain tactics. Choose targets in combat who have high strength, high courage, high firepower, low endurance, (to a smaller extent) high skill, rank and intelligence, and (to an even smaller extent) low speed.
Again, this is eyeball test only. But I'm amazed at how often (never mind how quickly) I'm double- and triple-teamed by Autobots and taken out of a fight within the first 30-45 seconds of a mission, especially in 1-10 and 1-11 missions where I have plenty of backup and it looks like it would be a pretty even fight for the most part. I typically have no less than two high-level opponents who start right off the bat going for my characters because it seems like I consistently become a target due to everyone's INT being higher than mine, or how my rank is so low, etc.
If anything, INT should be targeting the true threats, possibly determined by number of upgrades a character possesses -- a level 5, for instance, is not a true threat to a level 10+ character. Another 10+ character? That's the true threat, or at least I feel like that should be how it's evaluated. But it feels backwards to me that, a lot of times in missions, the Autobots start with me as one of the lowest-ranked Decepticons in those 1-10 and 1-11 missions, and work their way up to the highest-level characters. It's the only way I can see why it is we see level 10s and 11s consistently coming away from those missions with six-figure XP awards, while lower-level characters (this basically being level 6 and below) are almost always in the bottom of the XP gains, if they get anything at all.
Whew, this is more long-winded than I'd intended for this, I confess. Sorry about that.
