Cleric does not need a buff to its 1v1 or solo potential. Even with self heals taking a large nerf from Delf it has the tankiness and heals to survive. It also has the power to fight back; if you can out-melee the person you are against it is a win. It may still lose some matchups 1v1 but it can still win a bunch of them. Also if a class lacks hard CC or a good amount of silences/interrupts it does not have a good chance of winning.
I am not sure I understand why Cleric is less deserving of a complete rework then Ninja? Ninja is the 6th most played class in the game, barely behind Dragoon and Disciple. I don't really agree that a class that has almost 50% less use is less deserving, unless you are saying so because you think the more used classes need to be even better.
Druid on the other hand, as well as Shaman and BloodMage are also classes have has dismally low use and are not generally liked are I feel are just as deserving as Cleric.

Ninja:
It doesn't do what it is meant to do the majority of the time. Of course you can kill someone very quick if you are lucky and get the jump on them, hitting their back multiple times. Other times you don't have any tools at your disposal to get the back stab damage you need. The purpose of the Ninja rework would be having to not rely on 1 scenario over and over again. Not to mention the class is horrid in any group fight
But why is Ninja played so much?! It is because it is fun to play. In real world PvP you can escape just as much as a Dragoon. There are also very few Ninjas that can even PvP. Same goes for Dragoon; it may be good in some 1v1 matchups but most of the time it is considered 'bad'. People play it because it is fun, not because it is overly strong.
Cleric:
It does the job it is meant to do, and it does it really well. But if its so good why is it barely played?! It is not the most entertaining to play and being a dedicated healer does not suit the majority of people. I was fairly surprised when
@Darkwerty decided to be our Cleric because I always thought he preferred to be doing more damage. He made it work, he beat a good chunk of people 1v1 and still had a build that demolished in team fights.
It goes for the other classes too: Druid strong, Bloodmage strong, Beguiler strong, Bard strong. And the main reason Shaman is down there is because it is a broken class that never transitioned to a Caster.
I am a fan of making Cleric more interactive in every way. I like skill shot heals that require practice and aiming to use. But allowing Cleric to melee better does not make it more 'skillful' or 'interactive' considering Clerics can already go up in your face and melee you; it would just make what Cleric is doing right now stronger.
