Holy moly you guys, as soon as I saw the change in Invasion, I just HAD to write something about it!
I just can’t contain my excitement over this magnificent and marvelous development!
At first I was a bit concerned that some characters were missing, since I was used to seeing certain characters right off the bat, like Barbossa since I thought this week would be Yellow (which it technically still is), but then I scrolled further and looked more closely and saw that all characters are still present.
Get a load of this: THEY HAVE SIGNIFICANTLY IMPROVED THE REWARDS IN INVASION! JUST LOOK AT THEM!
Of course, the bad thing is that no Mod Upgrades were available, but considering that we’ve been getting Armor, Purple Skill, Normal and Fantastic Crit upgrades, this is definitely a breath of fresh air. Now we’re able to get new characters sooner, more money, more Mods; MORE EVERYTHING!
While this is great step in the right direction, especially since it appears that Perblue is listening to the fanbase, there is still more work to do.
The glaringly egregious part about this experimental update is that only a select ten heroes are Powered Up. Due to the fact that not everybody, understandably so, has/builds the same character, there’s a good chance that people will not be able to reap these rewards.
Should this “fourth” Invasion Week be a permanent installation into the game, then one thing I would suggest is to have ALL characters be Powered Up, as it makes this kind of Invasion more accessible to players - if all characters were to be Powered Up, then it would allow players to have more freedom in the kinds of teams they could craft for this kind of Invasion.
Adding onto that, in regular Invasion, if we didn’t have a character we wanted to Power Up, we could instead just apply a +1 to every character in the same Team. Unfortunately, we don’t have the option to at least apply a +1 to all characters; it’s restricted to the characters in the “Select Team” which is to say not very much, coming in at only 10 Heroes.
I apologize for overlooking the new problems that came with this update in my excitement 
Thank you to the people in the comments who pointed them out
One more aspect that seems to have changed, I think, is that the points acquired from defeating Boss Bots has been doubled! In the span of 20-30 minutes, I was able to hit Tier 17.
Does anybody have any pics of the points acquired from a previous Invasion to compare? Because I could have sworn the points used to be lower, ranging from 25-70.
As stated, this is a great start, and I look forward to seeing more of the feedback the community has provided being implemented. Thank you so much Perblue @Elliot @Polaris
