and
are fine for the first category you mentioned. Although to be fair Morello's IS crowding out Athenes. But I think that might be more because Athene's has to be balanced as a support item as well, either way I think it could use a small buff.
As far as the 'health rod' thing goes, you have a fuckton of options ranging from:
- gives everything you named except cdr, which ROA doesn't need.
- Gives everything you named PLUS cdr, PLUS a fifth ability (A flash that deals damage)
- Gives everything you named except the cdr, also includes a fifth ability (Minus the flash element, but the slow is pretty nice)
- No longer gives mana, but gives a decent amount of health and one of the most obnoxious slows in the game.
- health, ap, magic pen, and a consistent burn effect that makes deathfire touch redundant (at least imo)
and for damage that also gives mana you have:
- Doesn't give mana no, but it fits the 'small bonus damage' effect that you're looking for
- gives you mana, spellblade, cdr, movespeed, and a decent amount of AP
- gives health, mana, decent mana regen, and a mini
passive with Awe. Gives a godly shield in the late game when it becomes 
If you actually step back and take a look right now, mages are actually more spoiled for choice than almost any other class right now in terms of itemization. The only thing that's really annoying is that DESPITE the huge item diversity they seemingly have, Morello's is edging everything else out because it fits BOTH the utility of giving 20% cdr and mana regen out the ass, AND damage. which is why pretty much anything with a mana bar can blindly build it and still be effective. But I don't think the problem is with Morello's.
The problem is with the speed of the game right now.
The game is so fast that in order to keep up with everyone, mages NEED to hit 40-45% cdr ASAP in order to have their abilities up often enough to be able to contribute dick to a fight. But once they HAVE it, they actually need to have the damage to back it up so they are doing more than just performing a laser light show for his team that does little more than tickle people.
Fits both needs, mages don't HAVE to make a choice between damage and CDR with this thing, they can have both instantly. By its numbers it actually isn't a lot of flat damage, but the cdr lets them spam more to make up for that. While it brings JUST enough damage to the table for their hits to be noticeable.
Compound this with the fact that MR items for non tanks (
) Kind of suck right now so an opposing mid laner that isn't AD scaling (and thus can't just build
) can't even hope to itemize against it. And mid lane becomes a place where a fight between two mages is not decided by skill or strategy, but by who checked out their library book faster.
Note that my last sentence in this paragraph was a joke, I know just how much thought can actually go into a battle between two high damage mages, but sometimes it feels like that entire lane is decided by who finished morello's first. It isn't a great feeling when its not you, and it isn't very satisfying when it IS you, at least in my experience.
So why did I say things are fine?
Well to be honest, despite what I just said, we need an item like morellos, something that lets people quickly get their setup at the cost of specializing for either damage or utility. I know I just spent the past couple paragraphs making it sound like Morello's is OP but you can do that with any item by only describing its pro's, which I did when describing all of the options mages have. It is a very cookie cutter, generalist 'master of none' approach, the spamming is easily outplayed by someone who focused on pure damage and built something like
,
, or
early to match it and just knowing how to manage their cooldowns more effectively than the spambot. From there they just use the fact that their damage per hit is higher to exert lane pressure and eventually wear the other guy down. Or go the other route and avoid all ins while performing brief trades, while you wait for
to finish stacking. Using the survivability you have that the other guy doesn't to your advantage to stay in lane longer.
Basically, It's not very hard to outplay a Morello rush. It is very possible, it may be a dominant strategy that is crowding out other options at present, but I don't think it's inherently unhealthy to the game, and there are enough itemization paths for mages that you can pretty easily find something among their armory that works for your current situation to deal with it. It all depends on who you are facing that is rushing it.
