Dependency Mapper for Jira may be of help since it allows you to visualize dependencies between issues. You can choose how you want to group them, so see links based on project, Epic, fix version, or assignee, and then choose if you want to see the issues in a board, list, matrix or several other chart options.

We use Jira for project management and the ability to SEE all the issues that are blocking projects in "red" is fundamental.

Still struggling with this, I can't get approval for the plugins, just wish this were possible natively. 

I believe this is something common,

 i need to be able to query as following (as often requested by teamleads)

"Show me all Epics with their linked tickets" 

so roughly translated to JQL this would be something as following: 

Project = XX AND type = EPIC OR issue in (LinkedIssuesOf("isTaksOf", project = XX AND type = EPIC)) 

I'm also looking for a solution similar to this.  I was to query all items that caused a bug or more specifically, are linked by "is caused by".  As with he above issue, I'm not looking for linked issues of known items, but any item that been linked by the specified link.  Please tell me Jira has added this feature>

Bump, this is well needed

8 years and still missing in Cloud?

it can be achieved with SQL for JIRA:

issue in sql("
select othersissues.key
from issuestatusdefinitions s
inner join issues othersissues on s.id=othersissues .typeid
where othersissues .id in (
select myissues.id
from issuelinks l
inner join issues myissues on myissues.id=l.issueid
and
myissues.jql='(status = Open OR status = Reopened) AND assignee = currentUser()'
where l.type='Blocks' and l.direction='inward' )
and s.name in ('Open', 'Reopened')
") ORDER BY priority DESC, created ASC
