@Daojoan I agree.
Although I am a Jira Admin (sorry) and it’s something that can be done well…or not (usually more a case of business asking for the wrong things).
I view any claims “easily integrates with…” with huge skepticism in any system.
While I can see systems either specialise (good for some people) or try and do everything (“good enough” but users always think it’s designed for a different type of user), I can see how this “shattering of systems occurs”. You move away from a “good enough” all-encompassing system and then discover all the different ways your users were using the system you thought you knew - and how the replacements don’t do that.
…then eventually someone doesn’t want to pay all those bills and they try and standardise again (sigh).
