Hello Commander Johnny Spaceboots! and Commander Defacto!
Argh, just saw this as I was turning stuff off in the office! Must... Reply... (don't worry, that just means I enjoy the conversation).
Don't worry, we don't have to agree! And also, you may be right!
Sure, cells keep your shields up, but in my experience, when I'm taking a lot of hits from a ship I can't hit very well, having more shields doesn't help me destroy them...
Although at it's heart there will always be a whiff of the restorative about shield cells (because, well, they're consumables), it has always been the intention to involve timing skill in their use: this is why there is a delay when using a cell before the regenerative effect kicks in.
When the tweaks roll out, Commanders will have less of them, using them will be more expensive, and potentially they might have to alter or mess with their power plant settings to carry them.
If this proves to have little to no effect (and honestly, the jury is out for me at the moment, I will look forward to seeing the results) then we'll go further.
My first line of thought runs to some additional negative effect that triggers if a cell is used and the shield is not badly damaged, coupled with a longer delay between triggering a cell and receiving its benefits. In theory, this would mean that you would need to use a cell within a window of opportunity or risk A) leaving it too late and having the shield break or B) using it too soon and having something bad happen (like damage to your shield generator, or no benefit of the cell, etc.)
But, one step at a time.
And now, really for real this time, have a great weekend!
